Detailed Description

<<interface>> Listener for participant status.

Status Kinds

This is the interface that can be implemented by an application-provided class and then registered with the com.rti.dds.domain.DomainParticipant such that the application can be notified by RTI Connext of relevant status changes.

The com.rti.dds.domain.DomainParticipantListener interface extends all other Listener interfaces and has no additional operation beyond the ones defined by the more general listeners.

The purpose of the com.rti.dds.domain.DomainParticipantListener is to be the listener of last resort that is notified of all status changes not captured by more specific listeners attached to the com.rti.dds.infrastructure.DomainEntity objects. When a relevant status change occurs, RTI Connext will first attempt to notify the listener attached to the concerned com.rti.dds.infrastructure.DomainEntity if one is installed. Otherwise, RTI Connext will notify the Listener attached to the com.rti.dds.domain.DomainParticipant.

Important: Because a com.rti.dds.domain.DomainParticipantListener may receive callbacks pertaining to many different entities, it is possible for the same listener to receive multiple callbacks simultaneously in different threads. (Such is not the case for listeners of other types.) It is therefore critical that users of this listener provide their own protection for any thread-unsafe activities undertaken in a com.rti.dds.domain.DomainParticipantListener callback.

Note: Due to a thread-safety issue, the destruction of a DomainParticipantListener from an enabled DomainParticipant should be avoided – even if the DomainParticipantListener has been removed from the DomainParticipant. (This limitation does not affect the Java API.)
