Detailed Description

<<interface>> Container for all DDSDomainEntity objects.

The DomainParticipant object plays several roles:

It acts as a container for all other DDSEntity objects.

It acts as a factory for the DDSPublisher, DDSSubscriber, DDSTopic and DDSMultiTopic DDSEntity objects.

It represents the participation of the application on a communication plane that isolates applications running on the same set of physical computers from each other. A domain establishes a virtual network linking all applications that share the same domainId and isolating them from applications running on different domains. In this way, several independent distributed applications can coexist in the same physical network without interfering, or even being aware of each other.

It provides administration services in the domain, offering operations that allow the application to ignore locally any information about a given participant (DDSDomainParticipant::ignore_participant), publication (DDSDomainParticipant::ignore_publication), subscription (DDSDomainParticipant::ignore_subscription()) or topic (DDSDomainParticipant::ignore_topic()).

The following operations may be called even if the DDSDomainParticipant is not enabled. Operations NOT in this list will fail with DDS_RETCODE_NOT_ENABLED \ if called on a disabled DomainParticipant.

Operations for looking up topics: DDSDomainParticipant::lookup_topicdescription;

Operations that access status: DDSEntity::get_statuscondition, DDSEntity::get_status_changes.

QoS:: DDS_DomainParticipantQos

Status:: Status Kinds

Listener:: DDSDomainParticipantListener

Examples: HelloWorld_publisher.cxx, and HelloWorld_subscriber.cxx.

◆ register_contentfilter()

virtual DDS_ReturnCode_t DDSDomainParticipant::register_contentfilter	(	const char *	filter_name,
		const DDSContentFilter *	contentfilter
	)

pure virtual

<<extension>> Register a content filter which can be used to create a DDSContentFilteredTopic.

DDS specifies a SQL-like content filter for use by content filtered topics. If this filter does not meet your filtering requirements, you can register a custom filter.

To use a custom filter, it must be registered in the following places:

In any application that uses the custom filter to create a DDSContentFilteredTopic and the corresponding DDSDataReader.
In each application that writes the data to the applications mentioned above.

For example, suppose Application A on the subscription side creates a Topic named X and a ContentFilteredTopic named filteredX (and a corresponding DataReader), using a previously registered content filter, myFilter. With only that, you will have filtering at the subscription side. If you also want to perform filtering in any application that publishes Topic X, then you also need to register the same definition of the ContentFilter myFilter in that application.

Each filter_name can only be used to registered a content filter once with a DDSDomainParticipant.

Parameters

filter_name	<<in>> Name of the filter. The name must be unique within the DDSDomainParticipant and must not exceed 255 characters. Cannot be NULL.
contentfilter	<<in>> Content filter to be registered. Cannot be NULL.

Exceptions

One	of the Standard Return Codes

A filter_name can be unregistered only if it has been previously registered to the DDSDomainParticipant with DDSDomainParticipant::register_contentfilter.

The unregistration of filter is not allowed if there are any existing DDSContentFilteredTopic objects that are using the filter. If the operation is called on a filter with existing DDSContentFilteredTopic objects attached to it, this operation will fail with DDS_RETCODE_PRECONDITION_NOT_MET.

If there are still existing discovered DDSDataReader s with the same filter_name and the filter's compile method of the filter have previously been called on the discovered DDSDataReader s, finalize method of the filter will be called on those discovered DDSDataReader s before the content filter is unregistered. This means filtering will now be performed on the application that is creating the DDSDataReader.

Parameters

filter_name <<in>> Name of the filter. Cannot be NULL.

Exceptions

One	of the Standard Return Codes or DDS_RETCODE_PRECONDITION_NOT_MET

◆ get_default_profile_library()

virtual const char * DDSDomainParticipant::get_default_profile_library ( )

pure virtual

<<extension>> Gets the library where the default XML QoS profile is contained for a DDSDomainParticipant.

The default profile library is automatically set when DDSDomainParticipant::set_default_profile is called.

This library can be different than the DDSDomainParticipant default library (see DDSDomainParticipant::get_default_library).

Returns: The default profile library or null if the default profile was not set.

See also: DDSDomainParticipant::set_default_profile

◆ set_default_library()

virtual DDS_ReturnCode_t DDSDomainParticipant::set_default_library ( const char * library_name )

pure virtual

<<extension>> Sets the default XML library for a DDSDomainParticipant.

This method specifies the library that will be used as the default the next time a default library is needed during a call to one of this DomainParticipant's operations.

Any API requiring a library_name as a parameter can use null to refer to the default library.

If the default library is not set, the DDSDomainParticipant inherits the default from the DDSDomainParticipantFactory (see DDSDomainParticipantFactory::set_default_library).

Parameters

library_name <<in>> Library name. If library_name is null any previous default is unset.

Exceptions

	)

pure virtual

<<extension>> Sets the default XML profile for a DDSDomainParticipant.

This method specifies the profile that will be used as the default the next time a default DomainParticipant profile is needed during a call to one of this DomainParticipant's operations. When calling a DDSDomainParticipant method that requires a profile_name parameter, you can use NULL to refer to the default profile. (This same information applies to setting a default library.)

If the default profile is not set, the DDSDomainParticipant inherits the default from the DDSDomainParticipantFactory (see DDSDomainParticipantFactory::set_default_profile).

This method does not set the default QoS for entities created by the DDSDomainParticipant; for this functionality, use the methods set_default_<entity>_qos_with_profile (you may pass in NULL after having called set_default_profile()).

This method does not set the default QoS for newly created DomainParticipants; for this functionality, use DDSDomainParticipantFactory::set_default_participant_qos_with_profile.

Parameters

library_name	<<in>> The library name containing the profile.
profile_name	<<in>> The profile name. If profile_name is null any previous default is unset.

Exceptions

One	of the Standard Return Codes

	)

pure virtual

Creates a DDSContentFilteredTopic, that can be used to do content-based subscriptions.

The DDSContentFilteredTopic only relates to samples published under that DDSTopic, filtered according to their content. The filtering is done by means of evaluating a logical expression that involves the values of some of the data-fields in the sample.

◆ delete_contentfilteredtopic()

virtual DDS_ReturnCode_t DDSDomainParticipant::delete_contentfilteredtopic ( DDSContentFilteredTopic * a_contentfilteredtopic )

pure virtual

Deletes a DDSContentFilteredTopic.

Precondition: The deletion of a DDSContentFilteredTopic is not allowed if there are any existing DDSDataReader objects that are using the DDSContentFilteredTopic. If the operation is called on a DDSContentFilteredTopic with existing DDSDataReader objects attached to it, it will fail with DDS_RETCODE_PRECONDITION_NOT_MET.; The DDSContentFilteredTopic must be created by this DDSDomainParticipant, or else this operation will fail with DDS_RETCODE_PRECONDITION_NOT_MET.

MT Safety:: UNSAFE. It is not safe to delete an entity while another thread may be simultaneously calling an API that uses the entity.

Parameters

a_contentfilteredtopic <<in>>

Exceptions

One	of the Standard Return Codes or DDS_RETCODE_PRECONDITION_NOT_MET

◆ create_multitopic()

virtual DDSMultiTopic * DDSDomainParticipant::create_multitopic	(	const char *	name,
		const char *	type_name,
		const char *	subscription_expression,
		const DDS_StringSeq &	expression_parameters
	)

pure virtual

[Not supported (optional)] Creates a MultiTopic that can be used to subscribe to multiple topics and combine/filter the received data into a resulting type.

The resulting type is specified by the type_name argument. The list of topics and the logic used to combine, filter, and rearrange the information from each DDSTopic are specified using the subscription_expression and expression_parameters arguments.

Queries and Filters Syntax describes the syntax of subscription_expression and expression_parameters.

Precondition: The application is not allowed to create two DDSTopicDescription objects with the same name attached to the same DDSDomainParticipant. If the application attempts this, this method will fail and return NULL.; Prior to creating a DDSMultiTopic, the type must have been registered with RTI Connext. This is done using the FooTypeSupport::register_type operation on a derived class of the DDSTypeSupport interface. Otherwise, this method will return NULL.

Parameters

name	<<in>> Name of the newly create DDSMultiTopic. Cannot be NULL.
type_name	<<in>> Cannot be NULL.
subscription_expression	<<in>> Cannot be NULL.
expression_parameters	<<in>>

Returns: NULL

◆ delete_multitopic()

virtual DDS_ReturnCode_t DDSDomainParticipant::delete_multitopic ( DDSMultiTopic * a_multitopic )

pure virtual

[Not supported (optional)] Deletes a DDSMultiTopic.

Precondition: The deletion of a DDSMultiTopic is not allowed if there are any existing DDSDataReader objects that are using the DDSMultiTopic. If the delete_multitopic operation is called on a DDSMultiTopic with existing DDSDataReader objects attached to it, it will fail with DDS_RETCODE_PRECONDITION_NOT_MET.; The DDSMultiTopic must be created by this DDSDomainParticipant, or else this operation will fail with DDS_RETCODE_PRECONDITION_NOT_MET.

MT Safety:: UNSAFE. It is not safe to delete an entity while another thread may be simultaneously calling an API that uses the entity.

Parameters

a_multitopic <<in>>

◆ find_topic()

virtual DDSTopic * DDSDomainParticipant::find_topic	(	const char *	topic_name,
		const DDS_Duration_t &	timeout
	)

pure virtual

Finds an existing (or ready to exist) DDSTopic, based on its name.

This call can be used to block for a specified duration to wait for the DDSTopic to be created.

If the requested DDSTopic already exists, it is returned. Otherwise, find_topic() waits until another thread creates it or else returns when the specified timeout occurs.

find_topic() is useful when multiple threads are concurrently creating and looking up topics. In that case, one thread can call find_topic() and, if another thread has not yet created the topic being looked up, it can wait for some period of time for it to do so. In almost all other cases, it is more straightforward to call DDSDomainParticipant::lookup_topicdescription.

The DDSDomainParticipant must already be enabled.

Note: Each DDSTopic obtained by DDSDomainParticipant::find_topic must also be deleted by means of DDSDomainParticipant::delete_topic. If DDSTopic is obtained multiple times by means of DDSDomainParticipant::find_topic or DDSDomainParticipant::create_topic, it must also be deleted that same number of times using DDSDomainParticipant::delete_topic.

Parameters

topic_name	<<in>> Name of the DDSTopic to search for. Cannot be NULL.
timeout	<<in>> The time to wait if the DDSTopic does not exist already.

Returns: the topic, if it exists, or NULL

◆ lookup_topicdescription()

virtual DDSTopicDescription * DDSDomainParticipant::lookup_topicdescription ( const char * topic_name )

pure virtual

Looks up an existing, locally created DDSTopicDescription, based on its name.

DDSTopicDescription is the base class for DDSTopic, DDSMultiTopic and DDSContentFilteredTopic. So you can narrow the DDSTopicDescription returned from this operation to a DDSTopic or DDSContentFilteredTopic as appropriate.

Unlike DDSDomainParticipant::find_topic, which logically returns a new DDSTopic object that must be independently deleted, this operation returns a reference to the original local object.

The DDSDomainParticipant does not have to be enabled when you call lookup_topicdescription().

The returned topic may be either enabled or disabled.

MT Safety:: UNSAFE. It is not safe to lookup a topic description while another thread is creating that topic.

Parameters

topic_name <<in>> Name of DDSTopicDescription to search for. This string must be no more than 255 characters; it cannot be NULL.

Returns: The topic description, if it has already been created locally, otherwise it returns NULL.

◆ create_flowcontroller()

virtual DDSFlowController * DDSDomainParticipant::create_flowcontroller	(	const char *	name,
		const DDS_FlowControllerProperty_t &	prop
	)

pure virtual

<<extension>> Creates a DDSFlowController with the desired property.

The created DDSFlowController is associated with a DDSDataWriter via DDS_PublishModeQosPolicy::flow_controller_name. A single FlowController may service multiple DataWriters instances, even if they belong to a different DDSPublisher. The property determines how the FlowController shapes the network traffic.

Precondition: The specified property must be consistent, or the operation will fail and no DDSFlowController will be created.

MT Safety:: UNSAFE. If DDS_FLOW_CONTROLLER_PROPERTY_DEFAULT is used for property, it is not safe to create the flow controller while another thread may be simultaneously calling DDSDomainParticipant::set_default_flowcontroller_property or trying to lookup that flow controller with DDSDomainParticipant::lookup_flowcontroller.

Parameters

name	<<in>> name of the DDSFlowController to create. A DDSDataWriter is associated with a DDSFlowController by name. Limited to 255 characters.
prop	<<in>> property to be used for creating the new DDSFlowController. The special value DDS_FLOW_CONTROLLER_PROPERTY_DEFAULT can be used to indicate that the DDSFlowController should be created with the default DDS_FlowControllerProperty_t set in the DDSDomainParticipant.

Returns: Newly created flow controller object or NULL on failure.

See also: DDS_FlowControllerProperty_t for rules on consistency among property; DDS_FLOW_CONTROLLER_PROPERTY_DEFAULT; DDSDomainParticipant::get_default_flowcontroller_property

◆ delete_flowcontroller()

virtual DDS_ReturnCode_t DDSDomainParticipant::delete_flowcontroller ( DDSFlowController * fc )

pure virtual

<<extension>> Deletes an existing DDSFlowController.

Precondition: The DDSFlowController must not have any attached DDSDataWriter objects. If there are any attached DDSDataWriter objects, it will fail with DDS_RETCODE_PRECONDITION_NOT_MET.; The DDSFlowController must have been created by this DDSDomainParticipant, or else it will fail with DDS_RETCODE_PRECONDITION_NOT_MET.

Postcondition: The DDSFlowController is deleted if this method completes successfully.

MT Safety:: UNSAFE. It is not safe to delete an entity while another thread may be simultaneously calling an API that uses the entity.

Parameters

fc	<<in>> The DDSFlowController to be deleted.

Exceptions

One	of the Standard Return Codes, or DDS_RETCODE_PRECONDITION_NOT_MET.

◆ lookup_flowcontroller()

virtual DDSFlowController * DDSDomainParticipant::lookup_flowcontroller ( const char * name )

pure virtual

<<extension>> Looks up an existing locally-created DDSFlowController, based on its name.

Looks up a previously created DDSFlowController, including the built-in ones. Once a DDSFlowController has been deleted, subsequent lookups will fail.

MT Safety:: UNSAFE. It is not safe to lookup a flow controller description while another thread is creating that flow controller.

Parameters

name	<<in>> Name of DDSFlowController to search for. Limited to 255 characters. Cannot be NULL.

Returns: The flow controller if it has already been created locally, or NULL otherwise.

◆ get_builtin_subscriber()

virtual DDSSubscriber * DDSDomainParticipant::get_builtin_subscriber ( )

pure virtual

Accesses the built-in DDSSubscriber.

Each DDSDomainParticipant contains several built-in DDSTopic objects as well as corresponding DDSDataReader objects to access them. All of these DDSDataReader objects belong to a single built-in DDSSubscriber.

The built-in Topics are used to communicate information about other DDSDomainParticipant, DDSTopic, DDSDataReader, and DDSDataWriter objects.

The built-in subscriber is created when this operation is called for the first time. The built-in subscriber is deleted automatically when the DDSDomainParticipant is deleted.

Returns: The built-in DDSSubscriber singleton.

◆ ignore_participant()

virtual DDS_ReturnCode_t DDSDomainParticipant::ignore_participant ( const DDS_InstanceHandle_t & handle )

pure virtual

Instructs RTI Connext to locally ignore a remote DDSDomainParticipant.

From the time of this call onwards, RTI Connext will locally behave as if the remote participant did not exist. This means it will ignore any topic, publication, or subscription that originates on that DDSDomainParticipant.

There is no way to reverse this operation.

This operation can be used in conjunction with the discovery of remote participants offered by means of the DDS_ParticipantBuiltinTopicData to provide access control.

Application data can be associated with a DDSDomainParticipant by means of the USER_DATA policy. This application data is propagated as a field in the built-in topic and can be used by an application to implement its own access control policy.

The DDSDomainParticipant to ignore is identified by the handle argument. This handle is the one that appears in the DDS_SampleInfo retrieved when reading the data-samples available for the built-in DDSDataReader to the DDSDomainParticipant topic. The built-in DDSDataReader is read with the same FooDataReader::read and FooDataReader::take operations used for any DDSDataReader.

Parameters

handle <<in>> DDS_InstanceHandle_t of the DDSDomainParticipant to be ignored.

Exceptions

One	of the Standard Return Codes, DDS_RETCODE_OUT_OF_RESOURCES, DDS_RETCODE_NOT_ENABLED

See also: DDS_ParticipantBuiltinTopicData; DDS_PARTICIPANT_TOPIC_NAME; DDSDomainParticipant::get_builtin_subscriber

◆ banish_ignored_participants()

virtual DDS_ReturnCode_t DDSDomainParticipant::banish_ignored_participants ( )

pure virtual

<<extension>> Prevents ignored remote DomainParticipants from receiving traffic from the local DDSDomainParticipant.

This method complements DDSDomainParticipant::ignore_participant: ignore_participant prevents the local DDSDomainParticipant from processing traffic from the remote DomainParticipant, while this method prevents already ignored remote DomainParticipants from processing traffic from the local DomainParticipant.

Note: this method is currently only supported when enabling the RTI Security Plugins. Please refer to the RTI Security Plugins User's Manual for more information.

MT Safety:: Safe.

Exceptions

One	of the Standard Return Codes, DDS_RETCODE_PRECONDITION_NOT_MET, DDS_RETCODE_NOT_ENABLED

See also: DDSDomainParticipant::ignore_participant

◆ ignore_topic()

virtual DDS_ReturnCode_t DDSDomainParticipant::ignore_topic ( const DDS_InstanceHandle_t & handle )

pure virtual

Instructs RTI Connext to locally ignore a DDSTopic.

This means it will locally ignore any publication, or subscription to the DDSTopic.

There is no way to reverse this operation.

This operation can be used to save local resources when the application knows that it will never publish or subscribe to data under certain topics.

The DDSTopic to ignore is identified by the handle argument. This is the handle of a DDSTopic that appears in the DDS_SampleInfo retrieved when reading data samples from the built-in DDSDataReader for the DDSTopic.

Parameters

handle <<in>> Handle of the DDSTopic to be ignored.

Exceptions

One	of the Standard Return Codes, DDS_RETCODE_OUT_OF_RESOURCES or DDS_RETCODE_NOT_ENABLED

See also: DDS_TopicBuiltinTopicData; DDS_TOPIC_TOPIC_NAME; DDSDomainParticipant::get_builtin_subscriber

◆ ignore_publication()

virtual DDS_ReturnCode_t DDSDomainParticipant::ignore_publication ( const DDS_InstanceHandle_t & handle )

pure virtual

Instructs RTI Connext to locally ignore a publication.

A publication is defined by the association of a topic name, user data, and partition set on the DDSPublisher (see DDS_PublicationBuiltinTopicData). After this call, any data written by that publication's DDSDataWriter will be ignored.

This operation can be used to ignore local and remote DataWriters.

The publication (DataWriter) to ignore is identified by the handle argument.

To ignore a remote DataWriter, the handle can be obtained from the DDS_SampleInfo retrieved when reading data samples from the built-in DDSDataReader for the publication topic.

To ignore a local DataWriter, the handle can be obtained by calling DDSEntity::get_instance_handle for the local DataWriter.

There is no way to reverse this operation.

Parameters

handle <<in>> Handle of the DDSDataWriter to be ignored.

Exceptions

One	of the Standard Return Codes, DDS_RETCODE_OUT_OF_RESOURCES or DDS_RETCODE_NOT_ENABLED

See also: DDS_PublicationBuiltinTopicData; DDS_PUBLICATION_TOPIC_NAME; DDSDomainParticipant::get_builtin_subscriber

◆ ignore_subscription()

virtual DDS_ReturnCode_t DDSDomainParticipant::ignore_subscription ( const DDS_InstanceHandle_t & handle )

pure virtual

Instructs RTI Connext to locally ignore a subscription.

A subscription is defined by the association of a topic name, user data, and partition set on the DDSSubscriber (see DDS_SubscriptionBuiltinTopicData). After this call, any data received related to that subscription's DDSDataReader will be ignored.

This operation can be used to ignore local and remote DataReaders.

The subscription to ignore is identified by the handle argument.

To ignore a remote DataReader, the handle can be obtained from the DDS_SampleInfo retrieved when reading data samples from the built-in DDSDataReader for the subscription topic.

To ignore a local DataReader, the handle can be obtained by calling DDSEntity::get_instance_handle for the local DataReader.

There is no way to reverse this operation.

Parameters

handle <<in>> Handle of the DDSDataReader to be ignored.

Exceptions

One	of the Standard Return Codes, DDS_RETCODE_OUT_OF_RESOURCES or DDS_RETCODE_NOT_ENABLED

See also: DDS_SubscriptionBuiltinTopicData; DDS_SUBSCRIPTION_TOPIC_NAME; DDSDomainParticipant::get_builtin_subscriber

◆ get_domain_id()

virtual DDS_DomainId_t DDSDomainParticipant::get_domain_id ( )

pure virtual

Get the unique domain identifier.

This operation retrieves the domain id used to create the DDSDomainParticipant. The domain id identifies the DDS domain to which the DDSDomainParticipant belongs. Each DDS domain represents a separate data 'communication plane' isolated from other domains.

Returns: the unique domainId that was used to create the domain

See also: DDSDomainParticipantFactory::create_participant; DDSDomainParticipantFactory::create_participant_with_profile

◆ get_current_time()

virtual DDS_ReturnCode_t DDSDomainParticipant::get_current_time ( DDS_Time_t & current_time )

pure virtual

Returns the current value of the time.

The current value of the time that RTI Connext uses to time-stamp DDSDataWriter and to set the reception-timestamp for the data updates that it receives.

Parameters

current_time <<inout>> Current time to be filled up.

Exceptions

One	of the Standard Return Codes

◆ register_durable_subscription()

virtual DDS_ReturnCode_t DDSDomainParticipant::register_durable_subscription	(	const DDS_EndpointGroup_t &	group,
		const char *	topic_name
	)

pure virtual

<<extension>> Registers a Durable Subscription on the specified DDSTopic on all Persistence Services.

If you need to receive all samples published on a DDSTopic, including the ones published while a DDSDataReader is inactive or before it may be created, create a Durable Subscription using this method.

In this way, the Persistence Service will ensure that all the samples on that DDSTopic are retained until they are acknowledged by at least N DataReaders belonging to the Durable Subscription where N is the quorum count.

If the same Durable Subscription is created on a different DDSTopic, the Persistence Service will implicitly delete the previous Durable Subscription and create a new one on the new DDSTopic.

Parameters

group	<<in>> DDS_EndpointGroup_t The Durable Subscription name and quorum.
topic_name	<<in>> The topic name for which the Durable Subscription is created.

Exceptions

One	of the Standard Return Codes

◆ delete_durable_subscription()

virtual DDS_ReturnCode_t DDSDomainParticipant::delete_durable_subscription ( const DDS_EndpointGroup_t & group )

pure virtual

<<extension>> Deletes an existing Durable Subscription on all Persistence Services.

The Persistence Service will delete the Durable Subscription and the quorum of the existing samples will be considered satisfied.

Parameters

group <<in>> DDS_EndpointGroup_t specifying the Durable Subscription name. Quorum is not required for this operation.

Exceptions

One	of the Standard Return Codes

◆ assert_liveliness()

virtual DDS_ReturnCode_t DDSDomainParticipant::assert_liveliness ( )

pure virtual

Manually asserts the liveliness of this DDSDomainParticipant.

This is used in combination with the DDS_LivelinessQosPolicy to indicate to RTI Connext that the entity remains active.

You need to use this operation if the DDSDomainParticipant contains DDSDataWriter entities with the DDS_LivelinessQosPolicy::kind set to DDS_MANUAL_BY_PARTICIPANT_LIVELINESS_QOS and it only affects the liveliness of those DDSDataWriter entities. Otherwise, it has no effect.

Note: writing data via the FooDataWriter::write or FooDataWriter::write_w_timestamp operation asserts liveliness on the DDSDataWriter itself and its DDSDomainParticipant. Consequently the use of assert_liveliness() is only needed if the application is not writing data regularly.

Exceptions

One	of the Standard Return Codes, or DDS_RETCODE_NOT_ENABLED

See also: DDS_LivelinessQosPolicy

◆ resume_endpoint_discovery()

virtual DDS_ReturnCode_t DDSDomainParticipant::resume_endpoint_discovery ( const DDS_InstanceHandle_t & remote_participant_handle )

pure virtual

<<extension>> Initiates endpoint discovery with the specified remote DDSDomainParticipant.

If the operation returns DDS_RETCODE_OK, the DDSDomainParticipant will initiate endpoint discovery with the remote DDSDomainParticipant provided as a parameter.

When DDS_DiscoveryQosPolicy::enable_endpoint_discovery is set to DDS_BOOLEAN_FALSE, this operation allows the RTI Connext application to select for which remote DomainParticipants endpoint discovery is performed. By disabling endpoint discovery, the DomainParticipant will not store any state about remote endpoints and will not send local endpoint information to remote DomainParticipants.

If DDS_DiscoveryQosPolicy::enable_endpoint_discovery is set to DDS_BOOLEAN_TRUE, endpoint discovery will automatically occur for every discovered DDSDomainParticipant. In this case, invoking this operation will have no effect and will return DDS_RETCODE_OK.

When DDS_DiscoveryQosPolicy::enable_endpoint_discovery is set to DDS_BOOLEAN_FALSE, you have two options after a remote DDSDomainParticipant is discovered:

Call this operation to enable endpoint discovery. After invoking this operation, the DDSDomainParticipant will start to exchange endpoint information so that matching and communication can occur with the remote DDSDomainParticipant.
Call the DDSDomainParticipant::ignore_participant operation to permanently ignore endpoint discovery with the remote DDSDomainParticipant.

Setting DDS_DiscoveryQosPolicy::enable_endpoint_discovery to DDS_BOOLEAN_FALSE enables application-level authentication use cases, in which a DDSDomainParticipant will initiate endpoint discovery with a remote DDSDomainParticipant after successful authentication at the application level.

The remote_participant_handle paremeter is the one that appears in the DDS_SampleInfo retrieved when reading the data samples available for the built-in DDSParticipantBuiltinTopicDataDataReader.

If the specified remote DDSDomainParticipant is not in the database of discovered DomainParticipants or has been previously ignored, this operation will fail with DDS_RETCODE_ERROR.

This operation can be called multiple times on the same remote participant. If endpoint discovery has already been resumed, successive calls will have no effect and will return DDS_RETCODE_OK.

Parameters

remote_participant_handle <<in>> Handle of a discovered DDSDomainParticipant for which endpoint discovery is to be resumed.

Exceptions

One	of the Standard Return Codes,or DDS_RETCODE_NOT_ENABLED

See also: DDS_DiscoveryQosPolicy

◆ delete_contained_entities()

virtual DDS_ReturnCode_t DDSDomainParticipant::delete_contained_entities ( )

pure virtual

Delete all the entities that were created by means of the "create" operations on the DDSDomainParticipant.

This operation deletes all contained DDSPublisher (including an implicit Publisher, if one exists), DDSSubscriber (including implicit Subscriber), DDSTopic, DDSContentFilteredTopic, and DDSMultiTopic objects.

Prior to deleting each contained entity, this operation will recursively call the corresponding delete_contained_entities() operation on each contained entity (if applicable). This pattern is applied recursively. In this manner the operation delete_contained_entities() on the DDSDomainParticipant will end up recursively deleting all the entities contained in the DDSDomainParticipant, including the DDSDataWriter, DDSDataReader, as well as the DDSQueryCondition, DDSReadCondition, and DDSTopicQuery objects belonging to the contained DDSDataReader.

The operation will fail with DDS_RETCODE_PRECONDITION_NOT_MET if any of the contained entities is in a state where it cannot be deleted .

If delete_contained_entities() completes successfully, the application may delete the DDSDomainParticipant.

MT Safety:: UNSAFE. It is not safe to delete an entity while another thread may be simultaneously calling an API that uses the entity.

Exceptions

One	of the Standard Return Codes, or DDS_RETCODE_PRECONDITION_NOT_MET.

Examples: HelloWorld_publisher.cxx, and HelloWorld_subscriber.cxx.

	)

pure virtual

<<extension>> Returns a list of discovered DDSDomainParticipant entities that have the given DDS_EntityNameQosPolicy::name.

This operation retrieves the same list as DDSDomainParticipant::get_discovered_participants, except this list contains only the participants that have the given DDS_EntityNameQosPolicy::name.

Note: this method has different functionality when enabling the RTI Security Plugins. Please refer to the RTI Security Plugins User's Manual for more information.

MT Safety:: Safe.

Parameters

participant_handles	<<inout>> DDS_InstanceHandleSeq to be filled with handles of the discovered DDSDomainParticipant entities.
subject_name	<<in>> The DDS_EntityNameQosPolicy::name by which to filter the list.

		const DDS_InstanceHandle_t &	participant_handle
	)

pure virtual

Returns DDS_ParticipantBuiltinTopicData for the specified DDSDomainParticipant.

This operation retrieves information on a DDSDomainParticipant that has been discovered on the network. The participant must be in the same domain as the participant on which this operation is invoked and must not have been "ignored" by means of the DDSDomainParticipant::ignore_participant operation.

The participant_handle must correspond to such a DomainParticipant. Otherwise, the operation will fail with DDS_RETCODE_PRECONDITION_NOT_MET.

Use the operation DDSDomainParticipant::get_discovered_participants to find the DDSDomainParticipant entities that are currently discovered.

MT Safety:: Safe.

Parameters

		DDS_UnsignedLong &	subject_name_size,
		const DDS_InstanceHandle_t &	participant_handle
	)

pure virtual

<<extension>> Returns DDS_EntityNameQosPolicy::name for the specified DDSDomainParticipant.

This operation retrieves the DDS_EntityNameQosPolicy::name of a DDSDomainParticipant that has been discovered on the network. The participant must be in the same domain as the participant on which this operation is invoked and must not have been "ignored" by means of the DDSDomainParticipant::ignore_participant operation.

The participant_handle must correspond to such a DomainParticipant. If the participant_handle is DDS_HANDLE_NIL or is not a valid DDS_InstanceHandle_t for a DomainParticipant, then the operation will fail with DDS_RETCODE_BAD_PARAMETER. If the participant_handle corresponds to a DomainParticipant that has not been discovered, then the operation will fail with DDS_RETCODE_PRECONDITION_NOT_MET.

Use the operation DDSDomainParticipant::get_discovered_participants to find the DDSDomainParticipant entities that are currently discovered.

Note: this method has different functionality when enabling the RTI Security Plugins. Please refer to the RTI Security Plugins User's Manual for more information.

MT Safety:: Safe.

Parameters

subject_name	<<out>> The char buffer that will be used to store the DDS_EntityNameQosPolicy::name of the discovered DDSDomainParticipant. If NULL, this function will return the required length of this buffer through the subject_name_size parameter.
subject_name_size	<<inout>> Cannot be NULL. The size of the supplied char buffer. If the supplied buffer is NULL, or if the supplied buffer is not large enough, this value will be updated with the required length of the buffer, which includes space for the NUL terminator. If the supplied buffer is not NULL but this value is not large enough, then this function will fail with DDS_RETCODE_BAD_PARAMETER. If the DDS_EntityNameQosPolicy::name is NULL, then this value will be set to 0.

◆ contains_entity()

virtual DDS_Boolean DDSDomainParticipant::contains_entity ( const DDS_InstanceHandle_t & a_handle )

pure virtual

Completes successfully with DDS_BOOLEAN_TRUE if the referenced DDSEntity is contained by the DDSDomainParticipant.

This operation checks whether or not the given a_handle represents an DDSEntity that was created from the DDSDomainParticipant. The containment applies recursively. That is, it applies both to entities (DDSTopicDescription, DDSPublisher, or DDSSubscriber) created directly using the DDSDomainParticipant as well as entities created using a contained DDSPublisher, or DDSSubscriber as the factory, and so forth.

The instance handle for an DDSEntity may be obtained from built-in topic data, from various statuses, or from the operation DDSEntity::get_instance_handle.

◆ set_qos()

virtual DDS_ReturnCode_t DDSDomainParticipant::set_qos ( const DDS_DomainParticipantQos & qos )

pure virtual

Change the QoS of this DomainParticipant.

The DDS_DomainParticipantQos::user_data and DDS_DomainParticipantQos::entity_factory can be changed. The other policies are immutable.

Parameters

qos <<in>> Set of policies to be applied to DDSDomainParticipant. Policies must be consistent. Immutable policies cannot be changed after DDSDomainParticipant is enabled. The special value DDS_PARTICIPANT_QOS_DEFAULT can be used to indicate that the QoS of the DDSDomainParticipant should be changed to match the current default DDS_DomainParticipantQos set in the DDSDomainParticipantFactory.

Exceptions

One	of the Standard Return Codes, DDS_RETCODE_IMMUTABLE_POLICY if an immutable policy is changed, or DDS_RETCODE_INCONSISTENT_POLICY if policies are inconsistent

See also: DDS_DomainParticipantQos for rules on consistency among QoS policies; set_qos (abstract)

◆ set_qos_with_profile()

virtual DDS_ReturnCode_t DDSDomainParticipant::set_qos_with_profile	(	const char *	library_name,
		const char *	profile_name
	)

pure virtual

<<extension>> Change the QoS of this domain participant using the input XML QoS profile.

The DDS_DomainParticipantQos::user_data and DDS_DomainParticipantQos::entity_factory can be changed. The other policies are immutable.

Parameters

library_name	<<in>> Library name containing the XML QoS profile. If library_name is null RTI Connext will use the default library (see DDSDomainParticipantFactory::set_default_library).
profile_name	<<in>> XML QoS Profile name. If profile_name is null RTI Connext will use the default profile (see DDSDomainParticipantFactory::set_default_profile).

Exceptions

One	of the Standard Return Codes, DDS_RETCODE_IMMUTABLE_POLICY if immutable policy is changed, or DDS_RETCODE_INCONSISTENT_POLICY if policies are inconsistent

See also: DDS_DomainParticipantQos for rules on consistency among QoS

◆ get_qos()

virtual DDS_ReturnCode_t DDSDomainParticipant::get_qos ( DDS_DomainParticipantQos & qos )

pure virtual

Get the participant QoS.

This method may potentially allocate memory depending on the sequences contained in some QoS policies.

Parameters

qos	<<inout>> QoS to be filled up.

Exceptions

One	of the Standard Return Codes

See also: get_qos (abstract)

◆ add_peer()

virtual DDS_ReturnCode_t DDSDomainParticipant::add_peer ( const char * peer_desc_string )

pure virtual

<<extension>> Attempt to contact one or more additional peer participants.

Add the given peer description to the list of peers with which this DDSDomainParticipant will try to communicate.

This method may be called at any time after this DDSDomainParticipant has been created (before or after it has been enabled).

If this method is called after DDSEntity::enable, an attempt will be made to contact the new peer(s) immediately.

If this method is called before the DomainParticipant is enabled, the peer description will simply be added to the list that was populated by DDS_DiscoveryQosPolicy::initial_peers; the first attempted contact will take place after this DDSDomainParticipant is enabled.

Adding a peer description with this method does not guarantee that any peer(s) discovered as a result will exactly correspond to those described:

This DDSDomainParticipant will attempt to discover peer participants at the given locations but may not succeed if no such participants are available. In this case, this method will not wait for contact attempt(s) to be made and it will not report an error.

If remote participants described by the given peer description are discovered, the distributed application is configured with asymmetric peer lists, and DDS_DiscoveryQosPolicy::accept_unknown_peers is set to DDS_BOOLEAN_TRUE. Thus, this DDSDomainParticipant may actually discover more peers than are described in the given peer description.

To be informed of the exact remote participants that are discovered, regardless of which peers this DDSDomainParticipant attempts to discover, use the built-in participant topic: DDS_PARTICIPANT_TOPIC_NAME.

To remove specific peer locators, you may use DDSDomainParticipant::remove_peer. If a peer is removed, the add_peer operation will add it back to the list of peers.

To stop communicating with a peer DDSDomainParticipant that has been discovered, use DDSDomainParticipant::ignore_participant.

Adding a peer description with this method has no effect on the DDS_DiscoveryQosPolicy::initial_peers that may be subsequently retrieved with DDSDomainParticipant::get_qos() (because DDS_DiscoveryQosPolicy is immutable).

Parameters

peer_desc_string <<in>> New peer descriptor to be added. The format is specified in Peer Descriptor Format.

Exceptions

One	of the Standard Return Codes

See also: Peer Descriptor Format; DDS_DiscoveryQosPolicy::initial_peers; DDS_PARTICIPANT_TOPIC_NAME; DDSDomainParticipant::get_builtin_subscriber

◆ remove_peer()

virtual DDS_ReturnCode_t DDSDomainParticipant::remove_peer ( const char * peer_desc_string )

pure virtual

<<extension>> Remove one or more peer participants from the list of peers with which this DDSDomainParticipant will try to communicate.

This method may be called any time after this DDSDomainParticipant has been enabled

Calling this method has the following effects:

If a DDSDomainParticipant was already discovered, it will be locally removed along with all its entities.
Any further requests coming from a DDSDomainParticipant located on any of the removed peers will be ignored.
All the locators contained in the peer description will be removed from the peer list. The local DDSDomainParticipant will stop sending announcement to those locators.

If remote participants located on a peer that was previously removed are discovered, they will be ignored untill the related peer is added back by using DDSDomainParticipant::add_peer.

Removing a peer description with this method has no effect on the DDS_DiscoveryQosPolicy::initial_peers that may be subsequently retrieved with DDSDomainParticipant::get_qos() (because DDS_DiscoveryQosPolicy is immutable).

Parameters

peer_desc_string <<in>> Peer descriptor to be removed. The format is specified in Peer Descriptor Format.

Exceptions

One	of the Standard Return Codes

See also: Peer Descriptor Format; DDS_DiscoveryQosPolicy::initial_peers; DDSDomainParticipant::add_peer

◆ get_dns_tracker_polling_period()

virtual DDS_ReturnCode_t DDSDomainParticipant::get_dns_tracker_polling_period ( DDS_Duration_t & polling_period )

pure virtual

<<extension>> Retrieves the frequency used by the DNS tracker thread to query the DNS service.

The DNS tracker queries the DNS for hostnames specified in the initial peers of a DomainParticipant. The frequency of these queries is defined by DDS_DiscoveryConfigQosPolicy::dns_tracker_polling_period. If the value returned is DDS_DURATION_INFINITE, the DNS tracker is disabled.

Parameters

polling_period <<out>> Duration that the API populates with the period of the DNS tracker.

Exceptions

One	of the Standard Return Codes

See also: DDS_DiscoveryConfigQosPolicy::dns_tracker_polling_period

◆ set_dns_tracker_polling_period()

virtual DDS_ReturnCode_t DDSDomainParticipant::set_dns_tracker_polling_period ( const DDS_Duration_t & polling_period )

pure virtual

<<extension>> Configures the frequency in which the DNS tracker queries the DNS service.

This API allows you to change the frequency of the polling period for the DNS tracker. The range of accepted values, in seconds, goes from 1 second to 1 year. DDS_DURATION_INFINITE is also accepted as a valid value. If the duration is set to DDS_DURATION_INFINITE, the DNS tracker is disabled.

Modifying the DNS tracker polling period through this has no effect on the DDS_DiscoveryConfigQosPolicy::dns_tracker_polling_period when it is retrieved with DDSDomainParticipant::get_qos().

Parameters

polling_period <<in>> Duration that is set as the polling period for the DNS tracker.

Exceptions

One	of the Standard Return Codes

See also: DDS_DiscoveryConfigQosPolicy::dns_tracker_polling_period; DDSDomainParticipant::add_peer

◆ set_listener()

virtual DDS_ReturnCode_t DDSDomainParticipant::set_listener	(	DDSDomainParticipantListener *	l,
		DDS_StatusMask	mask = `DDS_STATUS_MASK_ALL`
	)

pure virtual

Sets the participant listener.

Parameters

l	<<in>> Listener to be installed on the entity.
mask	<<in>> Changes of communication status to be invoked on the listener. See DDS_StatusMask.

MT Safety:: Unsafe. This method is not synchronized with the listener callbacks, so it is possible to set a new listener on a participant when the old listener is in a callback.

Care should therefore be taken not to delete any listener that has been set on an enabled participant unless some application-specific means are available of ensuring that the old listener cannot still be in use.

Exceptions

One	of the Standard Return Codes

See also: set_listener (abstract)

◆ get_listener()

virtual DDSDomainParticipantListener * DDSDomainParticipant::get_listener ( )

pure virtual

Get the participant listener.

Returns: Existing listener attached to the DDSDomainParticipant.

See also: get_listener (abstract)

◆ get_implicit_publisher()

virtual DDSPublisher * DDSDomainParticipant::get_implicit_publisher ( )

pure virtual

<<extension>> Returns the implicit DDSPublisher. If an implicit Publisher does not already exist, this creates one.

There can only be one implicit Publisher per DomainParticipant.

The implicit Publisher is created with DDS_PUBLISHER_QOS_DEFAULT and no Listener.

This implicit Publisher will be deleted automatically when the following methods are called: DDSDomainParticipant::delete_contained_entities, or DDSDomainParticipant::delete_publisher with the implicit publisher as a parameter. Additionally, when a DomainParticipant is deleted, if there are no attached DataWriters that belong to the implicit Publisher, the implicit Publisher will be implicitly deleted.

Returns: The implicit publisher

See also: DDS_PUBLISHER_QOS_DEFAULT; DDSDomainParticipant::create_publisher

◆ get_implicit_subscriber()

virtual DDSSubscriber * DDSDomainParticipant::get_implicit_subscriber ( )

pure virtual

<<extension>> Returns the implicit DDSSubscriber. If an implicit Subscriber does not already exist, this creates one.

There can only be one implicit Subscriber per DomainParticipant.

The implicit Subscriber is created with DDS_SUBSCRIBER_QOS_DEFAULT and no Listener.

This implicit Subscriber will be deleted automatically when the following methods are called: DDSDomainParticipant::delete_contained_entities, or DDSDomainParticipant::delete_subscriber with the subscriber as a parameter. Additionally, when a DomainParticipant is deleted, if there are no attached DataReaders that belong to the implicit Subscriber, the implicit Subscriber will be implicitly deleted.

MT Safety:: UNSAFE. it is not safe to create the implicit subscriber while another thread may be simultaneously calling DDSDomainParticipant::set_default_subscriber_qos.

Returns: The implicit subscriber

Parameters

subscriber_name <<in>> Entity name of the DDSSubscriber.

Returns: The first DDSSubscriber found with the specified name or NULL if it is not found.

See also: DDSDomainParticipant::lookup_datareader_by_name

◆ lookup_datawriter_by_name()

virtual DDSDataWriter * DDSDomainParticipant::lookup_datawriter_by_name ( const char * datawriter_full_name )

pure virtual

<<extension>> Looks up a DDSDataWriter by its entity name within this DDSDomainParticipant.

Every DDSDataWriter in the system has an entity name which is configured and stored in the EntityName policy, ENTITY_NAME.

Every DDSPublisher in the system has an entity name which is also configured and stored in the EntityName policy.

This operation retrieves a DDSDataWriter within a DDSPublisher given the specified name which encodes both to the DDSDataWriter and the DDSPublisher name.

If there are several DDSDataWriter with the same name within the corresponding DDSPublisher this function returns the first matching occurrence.

The specified name might be given as a fully-qualified entity name or as a plain name.

The fully qualified entity name is a concatenation of the DDSPublisher to which the DDSDataWriter belongs and the entity name of of the DDSDataWriter itself, separated by a double colon "::". For example: MyPublisherName::MyDataWriterName

The plain name contains the DDSDataWriter name only. In this situation it is implied that the DDSDataWriter belongs to the implicit DDSPublisher so the use of a plain name is equivalent to specifying a fully qualified name with the DDSPublisher name part being "implicit". For example: the plain name "MyDataWriterName" is equivalent to specifiying the fully qualified name "implicit::MyDataWriterName"

The DDSDataWriter is only looked up within the DDSPublisher specified in the fully qualified name, or within the implicit DDSPublisher if the name was not fully qualified.

Parameters

datawriter_full_name <<in>> Entity name or fully-qualified entity name of the DDSDataWriter.

Returns: The first DDSDataWriter found with the specified name or NULL if it is not found.

Every DDSDataReader in the system has an entity name which is configured and stored in the EntityName policy, ENTITY_NAME.

Every DDSSubscriber in the system has an entity name which is also configured and stored in the EntityName policy, ENTITY_NAME.

This operation retrieves a DDSDataReader within a DDSSubscriber given the specified name which encodes both to the DDSDataReader and the DDSSubscriber name.

If there are several DDSDataReader with the same name within the corresponding DDSSubscriber this function returns the first matching occurrence.

The specified name might be given as a fully-qualified entity name or as a plain name.

The fully qualified entity name is a concatenation of the DDSSubscriber to which the DDSDataReader belongs and the entity name of of the DDSDataReader itself, separated by a double colon "::". For example: MySubscriberName::MyDataReaderName

The plain name contains the DDSDataReader name only. In this situation it is implied that the DDSDataReader belongs to the implicit DDSSubscriber so the use of a plain name is equivalent to specifying a fully qualified name with the DDSSubscriber name part being "implicit". For example: the plain name "MyDataReaderName" is equivalent to specifiying the fully qualified name "implicit::MyDataReaderName"

The DDSDataReader is only looked up within the DDSSubscriber specified in the fully qualified name, or within the implicit DDSSubscriber if the name was not fully qualified.

Parameters
