Detailed Description

<<interface>> Container for all DDS::DomainEntity objects.

The DomainParticipant object plays several roles:

  • It acts as a container for all other DDS::Entity 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.

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

void DDS::DomainParticipant::register_contentfilter ( System::String^  filter_name,
IContentFilter contentFilter 
)

<<extension>> [Not supported.] Register a content filter which can be used to create a DDS::ContentFilteredTopic.

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 DDS::ContentFilteredTopic and the corresponding DDS::DataReader.
  • 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 DDS::DomainParticipant.

Parameters
filter_name<<in>> Name of the filter. The name must be unique within the DDS::DomainParticipant and must not exceed 255 characters. Cannot be NULL.
contentfilter<<in>> Content filter to be registered. Cannot be NULL.
Exceptions
Oneof the Standard Return Codes
See Also
DDS::DomainParticipant::unregister_contentfilter
IContentFilter ^ DDS::DomainParticipant::lookup_contentfilter ( System::String^  filter_name)

<<extension>> [Not supported.] Lookup a content filter previously registered with DDS::DomainParticipant::register_contentfilter.

Parameters
filter_name<<in>> Name of the filter. Cannot be NULL.
Returns
NULL if the given filter_name has not been previously registered to the DDS::DomainParticipant with DDS::DomainParticipant::register_contentfilter. Otherwise, return the DDS::IContentFilter that has been previosuly registered with the given filter_name.
See Also
DDS::DomainParticipant::register_contentfilter
void DDS::DomainParticipant::unregister_contentfilter ( System::String^  filter_name)

<<extension>> [Not supported.] Unregister a content filter previously registered with DDS::DomainParticipant::register_contentfilter.

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

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

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

Parameters
filter_name<<in>> Name of the filter. Cannot be NULL.
Exceptions
Oneof the Standard Return Codes or DDS::Retcode_PreconditionNotMet
See Also
DDS::DomainParticipant::register_contentfilter
System::String ^ DDS::DomainParticipant::get_default_library ( )

<<extension>> Gets the default XML library associated with a DDS::DomainParticipant.

Returns
The default library or null if the default library was not set.
See Also
DDS::DomainParticipant::set_default_library
System::String ^ DDS::DomainParticipant::get_default_profile ( )

<<extension>> Gets the default XML profile associated with a DDS::DomainParticipant.

Returns
The default profile or null if the default profile was not set.
See Also
DDS::DomainParticipant::set_default_profile
System::String ^ DDS::DomainParticipant::get_default_profile_library ( )

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

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

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

Returns
The default profile library or null if the default profile was not set.
See Also
DDS::DomainParticipant::set_default_profile
void DDS::DomainParticipant::set_default_library ( System::String^  library_name)

<<extension>> Sets the default XML library for a DDS::DomainParticipant.

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 DDS::DomainParticipant inherits the default from the DDS::DomainParticipantFactory (see DDS::DomainParticipantFactory::set_default_library).

Parameters
library_name<<in>> Library name. If library_name is null any previous default is unset.
Exceptions
Oneof the Standard Return Codes
See Also
DDS::DomainParticipant::get_default_library
void DDS::DomainParticipant::set_default_profile ( System::String^  library_name,
System::String^  profile_name 
)

<<extension>> Sets the default XML profile for a DDS::DomainParticipant.

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 DDS::DomainParticipant 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 DDS::DomainParticipant inherits the default from the DDS::DomainParticipantFactory (see DDS::DomainParticipantFactory::set_default_profile).

This method does not set the default QoS for entities created by the DDS::DomainParticipant; 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 DDS::DomainParticipantFactory::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
Oneof the Standard Return Codes

One of the Standard Return Codes or DDS::Retcode_OutOfResources
void DDS::DomainParticipant::get_subscribers ( SubscriberSeq subscribers)

<<extension>> Allows the application to access all the subscribers the participant has.

If the sequence doesn't own its buffer, and its maximum is less than the total number of subscribers, it will be filled up to its maximum, and fail with DDS::Retcode_OutOfResources.

MT Safety:
Safe.
Parameters
subscribers<<inout>> a SubscriberSeq object where the set or list of subscribers will be returned
Returns
One of the Standard Return Codes or DDS::Retcode_OutOfResources
Topic ^ DDS::DomainParticipant::create_topic ( System::String^  topic_name,
System::String^  type_name,
TopicQos qos,
TopicListener listener,
StatusMask  mask 
)

Creates a DDS::Topic with the desired QoS policies and attaches to it the specified DDS::TopicListener.

Precondition
The application is not allowed to create two DDS::Topic objects with the same topic_name attached to the same DDS::DomainParticipant. If the application attempts this, this method will fail and return a NULL topic.
The specified QoS policies must be consistent, or the operation will fail and no DDS::Topic will be created.
Prior to creating a DDS::Topic, the type must have been registered with RTI Connext. This is done using the FooTypeSupport::register_type operation on a derived class of the DDS::TypeSupport interface.
MT Safety:
UNSAFE. It is not safe to create a topic while another thread is trying to lookup that topic description with DDS::DomainParticipant::lookup_topicdescription.
MT Safety:
UNSAFE. If DDS::DomainParticipant::TOPIC_QOS_DEFAULT is used for qos, it is not safe to create the topic while another thread may be simultaneously calling DDS::DomainParticipant::set_default_topic_qos.
Parameters
topic_name<<in>> Name for the new topic, must not exceed 255 characters. Cannot be NULL.
type_name<<in>> The type to which the new DDS::Topic will be bound. Cannot be NULL.
qos<<in>> QoS to be used for creating the new DDS::Topic. The special value DDS::DomainParticipant::TOPIC_QOS_DEFAULT can be used to indicate that the DDS::Topic should be created with the default DDS::TopicQos set in the DDS::DomainParticipant. Cannot be NULL.
listener<<in>>. Listener to be attached to the newly created DDS::Topic.
mask<<in>>. Changes of communication status to be invoked on the listener. See ::DDS::StatusMask.

void DDS::DomainParticipant::delete_topic ( Topic^ %  topic)

Deletes a DDS::Topic.

Precondition
If the DDS::Topic does not belong to the application's DDS::DomainParticipant, this operation fails with DDS::Retcode_PreconditionNotMet.
Make sure no objects are using the topic. More specifically, there must be no existing DDS::DataReader, DDS::DataWriter, DDS::ContentFilteredTopic, or DDS::MultiTopic objects belonging to the same DDS::DomainParticipant that are using the DDS::Topic. If delete_topic is called on a DDS::Topic with any of these existing objects attached to it, it will fail with DDS::Retcode_PreconditionNotMet.
Postcondition
Listener installed on the DDS::Topic will not be called after this method completes successfully.
Parameters
topic<<in>> DDS::Topic to be deleted.
Exceptions
Oneof the Standard Return Codes, or DDS::Retcode_PreconditionNotMet
ContentFilteredTopic ^ DDS::DomainParticipant::create_contentfilteredtopic ( System::String^  name,
Topic related_topic,
System::String^  filter_expression,
StringSeq expression_parameters 
)

Creates a DDS::ContentFilteredTopic, that can be used to do content-based subscriptions.

The DDS::ContentFilteredTopic only relates to samples published under that DDS::Topic, 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. The logical expression derived from the filter_expression and expression_parameters arguments.

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

Precondition
The application is not allowed to create two DDS::ContentFilteredTopic objects with the same topic_name attached to the same DDS::DomainParticipant. If the application attempts this, this method will fail and returns NULL.
If related_topic does not belong to this DDS::DomainParticipant, this operation returns NULL.
This function will create a content filter using the builtin SQL filter which implements a superset of the DDS specification. This filter requires that all IDL types have been compiled with typecodes. If this precondition is not met, this operation returns NULL. Do not use rtiddsgen's -notypecode option if you want to use the builtin SQL filter.
Parameters
name<<in>> Name for the new content filtered topic, must not exceed 255 characters. Cannot be NULL.
related_topic<<in>> DDS::Topic to be filtered. Cannot be NULL.
filter_expression<<in>> Cannot be NULL
expression_parameters<<in>> Cannot be NULL.An empty sequence must be used if the filter expression does not contain any parameters. Length of sequence cannot be greater than 100.
Returns
newly created DDS::ContentFilteredTopic, or NULL on failure
ContentFilteredTopic ^ DDS::DomainParticipant::create_contentfilteredtopic_with_filter ( System::String^  name,
Topic related_topic,
System::String^  filter_expression,
StringSeq expression_parameters,
System::String^  filter_name 
)

<<extension>> Creates a DDS::ContentFilteredTopic using the specified filter to do content-based subscriptions.

Parameters
name<<in>> Name for the new content filtered topic. Cannot exceed 255 characters. Cannot be NULL.
related_topic<<in>> DDS::Topic to be filtered. Cannot be NULL.
filter_expression<<in>> Cannot be NULL.
expression_parameters<<in>> Cannot be NULL.. An empty sequence must be used if the filter expression does not contain any parameters. Length of the sequence cannot be greater than 100.
filter_name<<in>> Name of content filter to use. Must previously have been registered with DDS::DomainParticipant::register_contentfilter on the same DDS::DomainParticipant. Cannot be NULL.

Builtin filter names are DDS::DomainParticipant::SQLFILTER_NAME and DDS::DomainParticipant::STRINGMATCHFILTER_NAME

Returns
newly created DDS::ContentFilteredTopic, or NULL on failure
void DDS::DomainParticipant::delete_contentfilteredtopic ( ContentFilteredTopic^ %  a_contentfilteredtopic)

Deletes a DDS::ContentFilteredTopic.

Precondition
The deletion of a DDS::ContentFilteredTopic is not allowed if there are any existing DDS::DataReader objects that are using the DDS::ContentFilteredTopic. If the operation is called on a DDS::ContentFilteredTopic with existing DDS::DataReader objects attached to it, it will fail with DDS::Retcode_PreconditionNotMet.
The DDS::ContentFilteredTopic must be created by this DDS::DomainParticipant, or else this operation will fail with DDS::Retcode_PreconditionNotMet.
Parameters
a_contentfilteredtopic<<in>>
Exceptions
Oneof the Standard Return Codes or DDS::Retcode_PreconditionNotMet
MultiTopic ^ DDS::DomainParticipant::create_multitopic ( System::String^  name,
System::String^  type_name,
System::String^  subscription_expression,
StringSeq expression_parameters 
)
inline

[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 DDS::Topic 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 ::DDS::TopicDescription objects with the same name attached to the same DDS::DomainParticipant. If the application attempts this, this method will fail and return NULL.
Prior to creating a DDS::MultiTopic, the type must have been registered with RTI Connext. This is done using the FooTypeSupport::register_type operation on a derived class of the DDS::TypeSupport interface. Otherwise, this method will return NULL.
Parameters
name<<in>> Name of the newly create DDS::MultiTopic. Cannot be NULL.
type_name<<in>> Cannot be NULL.
subscription_expression<<in>> Cannot be NULL.
expression_parameters<<in>> Cannot be NULL.
Returns
NULL
void DDS::DomainParticipant::delete_multitopic ( MultiTopic a_multitopic)
inline

[Not supported (optional)] Deletes a DDS::MultiTopic.

Precondition
The deletion of a DDS::MultiTopic is not allowed if there are any existing DDS::DataReader objects that are using the DDS::MultiTopic. If the delete_multitopic operation is called on a DDS::MultiTopic with existing DDS::DataReader objects attached to it, it will fail with DDS::Retcode_PreconditionNotMet.
The DDS::MultiTopic must be created by this DDS::DomainParticipant, or else this operation will fail with DDS::Retcode_PreconditionNotMet.
Parameters
a_multitopic<<in>>
Exceptions
DDS::Retcode_Unsupported
Topic ^ DDS::DomainParticipant::find_topic ( System::String^  topic_name,
Duration_t timeout 
)

Finds an existing (or ready to exist) DDS::Topic, based on its name.

This call can be used to block for a specified duration to wait for the DDS::Topic to be created.

If the requested DDS::Topic 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 DDS::DomainParticipant::lookup_topicdescription.

The DDS::DomainParticipant must already be enabled.

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

Parameters
topic_name<<in>> Name of the DDS::Topic to search for. Cannot be NULL.
timeout<<in>> The time to wait if the DDS::Topic does not exist already. Cannot be NULL.
Returns
the topic, if it exists, or NULL
ITopicDescription ^ DDS::DomainParticipant::lookup_topicdescription ( System::String^  topic_name)

Looks up an existing, locally created ::DDS::TopicDescription, based on its name.

::DDS::TopicDescription is the base class for DDS::Topic, DDS::MultiTopic and DDS::ContentFilteredTopic. So you can narrow the ::DDS::TopicDescription returned from this operation to a DDS::Topic or DDS::ContentFilteredTopic as appropriate.

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

The DDS::DomainParticipant 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 ::DDS::TopicDescription 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.
FlowController ^ DDS::DomainParticipant::create_flowcontroller ( System::String^  name,
FlowControllerProperty_t prop 
)

<<extension>> Creates a DDS::FlowController with the desired property.

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

Precondition
The specified property must be consistent, or the operation will fail and no DDS::FlowController 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 DDS::DomainParticipant::set_default_flowcontroller_property or trying to lookup that flow controller with DDS::DomainParticipant::lookup_flowcontroller.
Parameters
name<<in>> name of the DDS::FlowController to create. A DDS::DataWriter is associated with a DDS::FlowController by name. Limited to 255 characters.
prop<<in>> property to be used for creating the new DDS::FlowController. The special value ::DDS::FLOW_CONTROLLER_PROPERTY_DEFAULT can be used to indicate that the DDS::FlowController should be created with the default DDS::FlowControllerProperty_t set in the DDS::DomainParticipant. Cannot be NULL.
Returns
Newly created flow controller object or NULL on failure.

::DDS::FLOW_CONTROLLER_PROPERTY_DEFAULT
DDS::DomainParticipant::get_default_flowcontroller_property
void DDS::DomainParticipant::delete_flowcontroller ( FlowController^ %  fc)

<<extension>> Deletes an existing DDS::FlowController.

Precondition
The DDS::FlowController must not have any attached DDS::DataWriter objects. If there are any attached DDS::DataWriter objects, it will fail with DDS::Retcode_PreconditionNotMet.
The DDS::FlowController must have been created by this DDS::DomainParticipant, or else it will fail with DDS::Retcode_PreconditionNotMet.
Postcondition
The DDS::FlowController is deleted if this method completes successfully.
Parameters
fc<<in>> The DDS::FlowController to be deleted.
Exceptions
Oneof the Standard Return Codes, or DDS::Retcode_PreconditionNotMet.
FlowController ^ DDS::DomainParticipant::lookup_flowcontroller ( System::String^  name)

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

Looks up a previously created DDS::FlowController, including the built-in ones. Once a DDS::FlowController 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 DDS::FlowController to search for. Limited to 255 characters. Cannot be NULL.
Returns
The flow controller if it has already been created locally, or NULL otherwise.
Subscriber ^ DDS::DomainParticipant::get_builtin_subscriber ( )

Accesses the built-in DDS::Subscriber.

Each DDS::DomainParticipant contains several built-in DDS::Topic objects as well as corresponding DDS::DataReader objects to access them. All of these DDS::DataReader objects belong to a single built-in DDS::Subscriber.

The built-in Topics are used to communicate information about other DDS::DomainParticipant, DDS::Topic, DDS::DataReader, and DDS::DataWriter 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 DDS::DomainParticipant is deleted.

Returns
The built-in DDS::Subscriber singleton.

void DDS::DomainParticipant::ignore_participant ( InstanceHandle_t handle)

Instructs RTI Connext to locally ignore a remote DDS::DomainParticipant.

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 DDS::DomainParticipant.

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 DDS::DomainParticipant 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 DDS::DomainParticipant 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 DDS::DataReader to the DDS::DomainParticipant topic. The built-in DDS::DataReader is read with the same DDS::TypedDataReader::read and DDS::TypedDataReader::take operations used for any DDS::DataReader.

Parameters
handle<<in>> DDS::InstanceHandle_t of the DDS::DomainParticipant to be ignored. Cannot be NULL.
Exceptions
Oneof the Standard Return Codes, DDS::Retcode_OutOfResources, DDS::Retcode_NotEnabled
See Also
DDS::ParticipantBuiltinTopicData
DDS::ParticipantBuiltinTopicDataTypeSupport::PARTICIPANT_TOPIC_NAME
DDS::DomainParticipant::get_builtin_subscriber
void DDS::DomainParticipant::ignore_topic ( InstanceHandle_t handle)

Instructs RTI Connext to locally ignore a DDS::Topic.

This means it will locally ignore any publication, or subscription to the DDS::Topic.

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 DDS::Topic to ignore is identified by the handle argument. This is the handle of a DDS::Topic that appears in the DDS::SampleInfo retrieved when reading data samples from the built-in DDS::DataReader for the DDS::Topic.

Parameters
handle<<in>> Handle of the DDS::Topic to be ignored. Cannot be NULL.
Exceptions
Oneof the Standard Return Codes, DDS::Retcode_OutOfResources or DDS::Retcode_NotEnabled
See Also
DDS::TopicBuiltinTopicData
DDS::TopicBuiltinTopicDataTypeSupport::TOPIC_TOPIC_NAME
DDS::DomainParticipant::get_builtin_subscriber
void DDS::DomainParticipant::ignore_publication ( InstanceHandle_t handle)

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 DDS::Publisher (see DDS::PublicationBuiltinTopicData). After this call, any data written by that publication's DDS::DataWriter 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.

There is no way to reverse this operation.

Parameters
handle<<in>> Handle of the DDS::DataWriter to be ignored. Cannot be NULL.
Exceptions
Oneof the Standard Return Codes, DDS::Retcode_OutOfResources or DDS::Retcode_NotEnabled
See Also
DDS::PublicationBuiltinTopicData
DDS::PublicationBuiltinTopicDataTypeSupport::PUBLICATION_TOPIC_NAME
DDS::DomainParticipant::get_builtin_subscriber
void DDS::DomainParticipant::ignore_subscription ( InstanceHandle_t handle)

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 DDS::Subscriber (see DDS::SubscriptionBuiltinTopicData). After this call, any data received related to that subscription's DDS::DataReader will be ignored.

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

The subscription to ignore is identified by the handle argument.

There is no way to reverse this operation.

Parameters
handle<<in>> Handle of the DDS::DataReader to be ignored. Cannot be NULL.
Exceptions
Oneof the Standard Return Codes, DDS::Retcode_OutOfResources or DDS::Retcode_NotEnabled

DDS::SubscriptionBuiltinTopicData
DDS::SubscriptionBuiltinTopicDataTypeSupport::SUBSCRIPTION_TOPIC_NAME
DDS::DomainParticipant::get_builtin_subscriber
System::Int32 DDS::DomainParticipant::get_domain_id ( )

Get the unique domain identifier.

This operation retrieves the domain id used to create the DDS::DomainParticipant. The domain id identifies the DDS domain to which the DDS::DomainParticipant 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
DDS::DomainParticipantFactory::create_participant
DDS::DomainParticipantFactory::create_participant_with_profile
void DDS::DomainParticipant::get_current_time ( Time_t current_time)

Returns the current value of the time.

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

Parameters
current_time<<inout>> Current time to be filled up. Cannot be NULL.
Exceptions
Oneof the Standard Return Codes
void DDS::DomainParticipant::assert_liveliness ( )

Manually asserts the liveliness of this DDS::DomainParticipant.

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 DDS::DomainParticipant conatins DDS::DataWriter entities with the DDS::LivelinessQosPolicy::kind set to ::DDS::LivelinessQosPolicyKind::MANUAL_BY_PARTICIPANT_LIVELINESS_QOS and it only affects the liveliness of those DDS::DataWriter entities. Otherwise, it has no effect.

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

Exceptions
Oneof the Standard Return Codes, or DDS::Retcode_NotEnabled
See Also
DDS::LivelinessQosPolicy
void DDS::DomainParticipant::resume_endpoint_discovery ( InstanceHandle_t remote_participant_handle)

<<extension>> Initiates endpoint discovery with the specified remote DDS::DomainParticipant.

If the operation returns ::DDS::Exception::RETCODE_OK, the DDS::DomainParticipant will initiate endpoint discovery with the remote DDS::DomainParticipant provided as a parameter.

When DDS::DiscoveryQosPolicy::enable_endpoint_discovery is set to 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 true, endpoint discovery will automatically occur for every discovered DDS::DomainParticipant. In this case, invoking this operation will have no effect and will return ::DDS::Exception::RETCODE_OK.

When DDS::DiscoveryQosPolicy::enable_endpoint_discovery is set to false, you have two options after a remote DDS::DomainParticipant is discovered:

Setting DDS::DiscoveryQosPolicy::enable_endpoint_discovery to false enables application-level authentication use cases, in which a DDS::DomainParticipant will initiate endpoint discovery with a remote DDS::DomainParticipant 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 DDS::ParticipantBuiltinTopicDataDataReader.

If the specified remote DDS::DomainParticipant 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::Exception::RETCODE_OK.

Parameters
remote_participant_handle<<in>> Handle of a discovered DDS::DomainParticipant for which endpoint discovery is to be resumed. Cannot be NULL.
Exceptions
Oneof the Standard Return Codes,or DDS::Retcode_NotEnabled
See Also
DDS::DiscoveryQosPolicy
void DDS::DomainParticipant::delete_contained_entities ( )

Delete all the entities that were created by means of the "create" operations on the DDS::DomainParticipant.

This operation deletes all contained DDS::Publisher (including an implicit Publisher, if one exists), DDS::Subscriber (including implicit subscriber), DDS::Topic, DDS::ContentFilteredTopic, and DDS::MultiTopic 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 DDS::DomainParticipant will end up deleting all the entities recursively contained in the DDS::DomainParticipant, that is also the DDS::DataWriter, DDS::DataReader, as well as the DDS::QueryCondition and DDS::ReadCondition objects belonging to the contained DDS::DataReader.

The operation will fail with DDS::Retcode_PreconditionNotMet 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 DDS::DomainParticipant knowing that it has no contained entities.

Exceptions
Oneof the Standard Return Codes, or DDS::Retcode_PreconditionNotMet.
Examples:
HelloWorld_publisher.cpp, and HelloWorld_subscriber.cpp.
void DDS::DomainParticipant::get_discovered_participants ( InstanceHandleSeq participant_handles)

Returns a list of discovered DDS::DomainParticipant entities.

This operation retrieves the list of DDS::DomainParticipant entities that have been discovered in the domain and that the application has not indicated should be "ignored" by means of the DDS::DomainParticipant::ignore_participant operation.

Parameters
participant_handles<<inout>> DDS::InstanceHandleSeq to be filled with handles of the discovered DDS::DomainParticipant entities.
Exceptions
Oneof the Standard Return Codes or DDS::Retcode_NotEnabled
void DDS::DomainParticipant::get_discovered_participant_data ( ParticipantBuiltinTopicData participant_data,
InstanceHandle_t participant_handle 
)

Returns DDS::ParticipantBuiltinTopicData for the specified DDS::DomainParticipant.

This operation retrieves information on a DDS::DomainParticipant 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 DDS::DomainParticipant::ignore_participant operation.

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

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

Note: This operation does not retrieve the ::DDS::ParticipantBuiltinTopicData::property. This information is available through DDS::DataReaderListener::on_data_available() (if a reader listener is installed on the DDS::ParticipantBuiltinTopicDataDataReader).

MT Safety:
Unsafe. It is not safe to call this operation from multiple threads at the same time.
Parameters
participant_data<<inout>> DDS::ParticipantBuiltinTopicData to be filled in with the data for the specified DDS::DomainParticipant.
participant_handle<<in>> DDS::InstanceHandle_t of DDS::DomainParticipant.

)

Returns DDS::TopicBuiltinTopicData for the specified DDS::Topic.

This operation retrieves information on a DDS::Topic that has been discovered by the local Participant and must not have been "ignored" by means of the DDS::DomainParticipant::ignore_topic operation.

The topic_handle must correspond to such a topic. Otherwise, the operation will fail with DDS::Retcode_PreconditionNotMet.

This call is not supported for remote topics. If a remote topic_handle is used, the operation will fail with DDS::Retcode_Unsupported.

Use the operation DDS::DomainParticipant::get_discovered_topics to find the topics that are currently discovered.

Parameters
topic_data<<inout>> DDS::TopicBuiltinTopicData to be filled with the specified DDS::Topic's data.
topic_handle<<in>> DDS::InstanceHandle_t of DDS::Topic.

System::Boolean DDS::DomainParticipant::contains_entity ( InstanceHandle_t a_handle)

Completes successfully with true if the referenced DDS::Entity is contained by the DDS::DomainParticipant.

This operation checks whether or not the given a_handle represents an DDS::Entity that was created from the DDS::DomainParticipant. The containment applies recursively. That is, it applies both to entities (::DDS::TopicDescription, DDS::Publisher, or DDS::Subscriber) created directly using the DDS::DomainParticipant as well as entities created using a contained DDS::Publisher, or DDS::Subscriber as the factory, and so forth.

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

Parameters
a_handle<<in>> DDS::InstanceHandle_t of the DDS::Entity to be checked.
Returns
true if DDS::Entity is contained by the DDS::DomainParticipant, or false otherwise.
void DDS::DomainParticipant::set_qos ( DomainParticipantQos qos)

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 DDS::DomainParticipant. Policies must be consistent. Immutable policies cannot be changed after DDS::DomainParticipant is enabled. The special value DDS::DomainParticipantFactory::PARTICIPANT_QOS_DEFAULT can be used to indicate that the QoS of the DDS::DomainParticipant should be changed to match the current default DDS::DomainParticipantQos set in the DDS::DomainParticipantFactory. Cannot be NULL.
Exceptions
Oneof the Standard Return Codes, DDS::Retcode_ImmutablePolicy if an immutable policy is changed, or DDS::Retcode_InconsistentPolicy if policies are inconsistent

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 DDS::DomainParticipantFactory::set_default_library).
profile_name<<in>> XML QoS Profile name. If profile_name is null RTI Connext will use the default profile (see DDS::DomainParticipantFactory::set_default_profile).
Exceptions
Oneof the Standard Return Codes, DDS::Retcode_ImmutablePolicy if immutable policy is changed, or DDS::Retcode_InconsistentPolicy if policies are inconsistent

void DDS::DomainParticipant::get_qos ( DomainParticipantQos qos)

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. Cannot be NULL.
Exceptions
Oneof the Standard Return Codes

void DDS::DomainParticipant::add_peer ( System::String^  peer_desc_string)

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

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

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

If this method is called after DDS::Entity::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 DDS::DomainParticipant 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 DDS::DomainParticipant 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.

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

To remove specific peer locators, you may use DDS::DomainParticipant::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 DDS::DomainParticipant that has been discovered, use DDS::DomainParticipant::ignore_participant.

Adding a peer description with this method has no effect on the DDS::DiscoveryQosPolicy::initial_peers that may be subsequently retrieved with DDS::DomainParticipant::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. Cannot be NULL.
Exceptions
Oneof the Standard Return Codes

void DDS::DomainParticipant::remove_peer ( System::String^  peer_desc_string)

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

This method may be called any time after this DDS::DomainParticipant has been enabled

Calling this method has the following effects:

  • If a DDS::DomainParticipant was already discovered, it will be locally removed along with all its entities.
  • Any further requests coming from a DDS::DomainParticipant 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 DDS::DomainParticipant 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 DDS::DomainParticipant::add_peer.

Removing a peer description with this method has no effect on the DDS::DiscoveryQosPolicy::initial_peers that may be subsequently retrieved with DDS::DomainParticipant::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. Cannot be NULL.
Exceptions
Oneof the Standard Return Codes

void DDS::DomainParticipant::set_listener ( DomainParticipantListener l,
StatusMask  mask 
)

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.
Exceptions
Oneof the Standard Return Codes

set_listener (abstract)
DomainParticipantListener ^ DDS::DomainParticipant::get_listener ( )

Get the participant listener.

Returns
Existing listener attached to the DDS::DomainParticipant.

Entity_get_listener
virtual void DDS::DomainParticipant::enable ( )
overridevirtual

Enables the DDS::Entity.

This operation enables the Entity. Entity objects can be created either enabled or disabled. This is controlled by the value of the ENTITY_FACTORY QoS policy on the corresponding factory for the DDS::Entity.

By default, ENTITY_FACTORY is set so that it is not necessary to explicitly call DDS::Entity::enable on newly created entities.

The DDS::Entity::enable operation is idempotent. Calling enable on an already enabled Entity returns OK and has no effect.

If a DDS::Entity has not yet been enabled, the following kinds of operations may be invoked on it:

Other operations may explicitly state that they may be called on disabled entities; those that do not will return the error DDS::Retcode_NotEnabled.

It is legal to delete an DDS::Entity that has not been enabled by calling the proper operation on its factory.

Entities created from a factory Entity that is disabled are created disabled, regardless of the setting of the DDS::EntityFactoryQosPolicy.

Calling enable on an Entity whose factory Entity is not enabled will fail and return DDS::Retcode_PreconditionNotMet.

If DDS::EntityFactoryQosPolicy::autoenable_created_entities is TRUE, the enable operation on a factory will automatically enable all entities created from that factory (for example, enabling a DDS::Publisher will enable all its contained DDS::DataWriter objects)

Listeners associated with an entity are not called until the entity is enabled.

Conditions associated with a disabled entity are "inactive," that is, they have a trigger_value == FALSE.

Exceptions
Oneof the Standard Return Codes, Standard Return Codes or DDS::Retcode_PreconditionNotMet.

Implements DDS::Entity.

virtual StatusCondition ^ DDS::DomainParticipant::get_statuscondition ( )
overridevirtual

Allows access to the DDS::StatusCondition associated with the DDS::Entity.

The returned condition can then be added to a DDS::WaitSet so that the application can wait for specific status changes that affect the DDS::Entity.

Returns
the status condition associated with this entity.

Implements DDS::Entity.

virtual StatusMask DDS::DomainParticipant::get_status_changes ( )
overridevirtual

Retrieves the list of communication statuses in the DDS::Entity that are triggered.

That is, the list of statuses whose value has changed since the last time the application read the status using the get_*_status() method.

When the entity is first created or if the entity is not enabled, all communication statuses are in the "untriggered" state so the list returned by the get_status_changes operation will be empty.

The list of statuses returned by the get_status_changes operation refers to the status that are triggered on the Entity itself and does not include statuses that apply to contained entities.

Returns
list of communication statuses in the DDS::Entity that are triggered.

Status Kinds

Implements DDS::Entity.

virtual InstanceHandle_t DDS::DomainParticipant::get_instance_handle ( )
overridevirtual

Allows access to the DDS::InstanceHandle_t associated with the DDS::Entity.

This operation returns the DDS::InstanceHandle_t that represents the DDS::Entity.

Returns
the instance handle associated with this entity.

Implements DDS::Entity.

Publisher ^ DDS::DomainParticipant::lookup_publisher_by_name ( String^  publisher_name)

<<extension>> Looks up a DDS::Publisher by its entity name within this DDS::DomainParticipant.

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

This operation retrieves a DDS::Publisher within the DDS::DomainParticipant given the entity's name. If there are several DDS::Publisher with the same name within the DDS::DomainParticipant, this function returns the first matching occurrence.

Parameters
publisher_name<<in>> Entity name of the DDS::Publisher.
Returns
The first DDS::Publisher found with the specified name or NULL if it is not found.

DDS::DomainParticipant::lookup_datawriter_by_name
Subscriber ^ DDS::DomainParticipant::lookup_subscriber_by_name ( String^  subscriber_name)

<<extension>> Retrieves a DDS::Subscriber by its entity name within this DDS::DomainParticipant.

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

This operation retrieves a DDS::Subscriber within the DDS::DomainParticipant given the entity's name. If there are several DDS::Subscriber with the same name within the DDS::DomainParticipant, this function returns the first matching occurrence.

Parameters
subscriber_name<<in>> Entity name of the DDS::Subscriber.
Returns
The first DDS::Subscriber found with the specified name or NULL if it is not found.
