Detailed Description

Object describing a remote Publication.

This object contains all of the information about a remote DDSDataWriter and its DDSPublisher that is necessary for matching the remote DDSDataWriter to a local DDSDataReader during discovery.

This object is used to pre-configure remote entities for Dynamic Participant/Static Endpoint discovery.

For example: Application A is designed to discover a remote DDSDataWriter in application B, and that remote DDSDataWriter has an object ID of 100, and a deadline of three seconds. In Dynamic Participant/Static Endpoint discovery, this discovery data is not sent over the network, so the user must create an instance of a DDS_PublicationBuiltinTopicData structure in application A. The user then must fill in the QoS describing this remote DDSDataWriter, including the writer's object ID and three-second deadline. Then the user must assert this DDS_PublicationBuiltinTopicData describing the remote entity with the discovery plugin. The pre-configured QoS must match the actual QoS of the remote entity, or communication will not occur.
