Public Functions
-
DomainParticipantListener
()¶ Constructor.
-
~DomainParticipantListener
()¶ Destructor.
-
void
on_participant_discovery
(DomainParticipant *participant, fastrtps::rtps::ParticipantDiscoveryInfo &&info)¶ This method is called when a new Participant is discovered, or a previously discovered participant changes its QOS or is removed.
- Parameters
participant
: Pointer to the Participant which discovered the remote participant.info
: Remote participant information. User can take ownership of the object.
-
void
onParticipantAuthentication
(DomainParticipant *participant, fastrtps::rtps::ParticipantAuthenticationInfo &&info)¶ This method is called when a new Participant is authenticated.
- Parameters
participant
: Pointer to the authenticated Participant.info
: Remote participant authentication information. User can take ownership of the object.
-
void
on_subscriber_discovery
(DomainParticipant *participant, fastrtps::rtps::ReaderDiscoveryInfo &&info)¶ This method is called when a new Subscriber is discovered, or a previously discovered subscriber changes its QOS or is removed.
- Parameters
participant
: Pointer to the Participant which discovered the remote subscriber.info
: Remote subscriber information. User can take ownership of the object.
-
void
on_publisher_discovery
(DomainParticipant *participant, fastrtps::rtps::WriterDiscoveryInfo &&info)¶ This method is called when a new Publisher is discovered, or a previously discovered publisher changes its QOS or is removed.
- Parameters
participant
: Pointer to the Participant which discovered the remote publisher.info

-
void
on_type_discovery
(DomainParticipant *participant, const fastrtps::rtps::SampleIdentity &request_sample_id, const fastrtps::string_255 &topic, const fastrtps::types::TypeIdentifier *identifier, const fastrtps::types::TypeObject *object, fastrtps::types::DynamicType_ptr dyn_type)¶ This method is called when a participant discovers a new Type The ownership of all object belongs to the caller so if needs to be used after the method ends, a full copy should be perform (except for dyn_type due to its shared_ptr nature.
For example: fastrtps::types::TypeIdentifier new_type_id = *identifier;
-
void
on_type_dependencies_reply
(DomainParticipant *participant, const fastrtps::rtps::SampleIdentity &request_sample_id, const fastrtps::types::TypeIdentifierWithSizeSeq &dependencies)¶ This method is called when the typelookup client received a reply to a getTypeDependencies request.
The user may want to retrieve these new types using the getTypes request and create a new DynamicType using the retrieved TypeObject.
-
void
on_type_information_received
(DomainParticipant *participant, const fastrtps::string_255 topic_name, const fastrtps::string_255 type_name, const fastrtps::types::TypeInformation &type_information)¶ This method is called when a participant receives a TypeInformation while discovering another participant.
