The DomainParticipant object plays several roles:
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 DDSDomainParticipant is not enabled. Operations NOT in this list will fail with DDS_RETCODE_NOT_ENABLED \ if called on a disabled DomainParticipant.

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:
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.
| 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. |
|
pure virtual |
<<extension>> Lookup a content filter previously registered with DDSDomainParticipant::register_contentfilter.
| filter_name | <<in>> Name of the filter. Cannot be NULL. |
|
pure virtual |
<<extension>> Unregister a content filter previously registered with DDSDomainParticipant::register_contentfilter.
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.
| filter_name | <<in>> Name of the filter. Cannot be NULL. |
|

|
pure virtual |
<<extension>> Gets the default XML profile associated with a DDSDomainParticipant.
|
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).
|
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).
| library_name | <<in>> Library name. If library_name is null any previous default is unset. |
|
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.
| 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. |

This method may potentially allocate memory depending on the sequences contained in some QoS policies.
If DDS_PUBLISHER_QOS_DEFAULT is specified as the qos parameter when DDSDomainParticipant::create_topic is called, the default value of the QoS set in the factory, equivalent to the value obtained by calling DDSDomainParticipant::get_default_publisher_qos, will be used to create the DDSPublisher.

This method may potentially allocate memory depending on the sequences contained in some QoS policies.
If DDS_SUBSCRIBER_QOS_DEFAULT is specified as the qos parameter when DDSDomainParticipant::create_subscriber is called, the default value of the QoS set in the factory, equivalent to the value obtained by calling DDSDomainParticipant::get_default_subscriber_qos, will be used to create the DDSSubscriber.

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.

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.

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.

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.

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.

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.
handle can be obtained from the DDS_SampleInfo retrieved when reading data samples from the built-in DDSDataReader for the publication topic. handle can be obtained by calling DDSEntity::get_instance_handle for the local DataWriter. There is no way to reverse this operation.
| handle | <<in>> Handle of the DDSDataWriter to be ignored. |

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.
handle can be obtained from the DDS_SampleInfo retrieved when reading data samples from the built-in DDSDataReader for the subscription topic. handle can be obtained by calling DDSEntity::get_instance_handle for the local DataReader. There is no way to reverse this operation.

<<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.

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.

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

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 deleting all the entities recursively contained in the DDSDomainParticipant, that is also the DDSDataWriter, DDSDataReader, as well as the DDSQueryCondition and DDSReadCondition 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 knowing that it has no contained entities.

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.
Note: This operation does not retrieve the DDS_ParticipantBuiltinTopicData::property. This information is available through DDSDataReaderListener::on_data_available() (if a reader listener is installed on the DDSParticipantBuiltinTopicDataDataReader).

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:
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).

<<extension>> Deletes a DDSDataWriter that belongs to the implicit DDSPublisher.
The deletion of the DDSDataWriter will automatically unregister all instances. Depending on the settings of the WRITER_DATA_LIFECYCLE QosPolicy, the deletion of the DDSDataWriter may also dispose all instances.
If the DataWriter's DDS_DestinationOrderQosPolicy::kind is DDS_BY_SOURCE_TIMESTAMP_DESTINATIONORDER_QOS, calls to delete_datawriter() may fail if your application has previously used the 'with timestamp' APIs (write_w_timestamp(), register_instance_w_timestamp(), unregister_instance_w_timestamp(), or dispose_w_timestamp()) with a timestamp larger (later) than the time at which delete_datawriter() is called. To prevent delete_datawriter() from failing in this situation, either:

<<extension>> Creates a DDSDataReader that will be attached and belong to the implicit DDSSubscriber.
The DDSDataReader created using this method will be associated with the implicit Subscriber. This Subscriber is automatically created (if it does not exist) using DDS_SUBSCRIBER_QOS_DEFAULT when the following methods are called: DDSDomainParticipant::create_datareader, DDSDomainParticipant::create_datareader_with_profile, or DDSDomainParticipant::get_implicit_subscriber.
qos parameter, it is not safe to create the datareader while another thread may be simultaneously calling DDSDomainParticipant::set_default_datareader_qos. | topic | <<in>> The DDSTopicDescription that the DDSDataReader will be associated with. |
| qos | <<in>> The qos of the DDSDataReader. The special value DDS_DATAREADER_QOS_DEFAULT can be used to indicate that the DDSDataReader should be created with the default DDS_DataReaderQos set in the implicit DDSSubscriber. If DDSTopicDescription is of type DDSTopic or DDSContentFilteredTopic, the special value DDS_DATAREADER_QOS_USE_TOPIC_QOS can be used to indicate that the DDSDataReader should be created with the combination of the default DDS_DataReaderQos set on the implicit DDSSubscriber and the DDS_TopicQos (in the case of a DDSContentFilteredTopic, the DDS_TopicQos of the related DDSTopic). if DDS_DATAREADER_QOS_USE_TOPIC_QOS is used, topic cannot be a DDSMultiTopic. |

<<extension>> Looks up a DDSPublisher by its entity name within this DDSDomainParticipant.
Every DDSPublisher in the system has an entity name which is configured and stored in the EntityName policy, ENTITY_NAME.
This operation retrieves a DDSPublisher within the DDSDomainParticipant given the entity's name. If there are several DDSPublisher with the same name within the DDSDomainParticipant, this function returns the first matching occurrence.
| publisher_name | <<in>> Entity name of the DDSPublisher. |

pure virtual |
<<extension>> Retrieves a DDSSubscriber by its entity name within this DDSDomainParticipant.
Every DDSSubscriber in the system has an entity name which is configured and stored in the EntityName policy, ENTITY_NAME.
This operation retrieves a DDSSubscriber within the DDSDomainParticipant given the entity's name. If there are several DDSSubscriber with the same name within the DDSDomainParticipant, this function returns the first matching occurrence.
| subscriber_name | <<in>> Entity name of the DDSSubscriber. |

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

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.
