Detailed Description

The key type of the built-in topic types.

Each remote DDSEntity to be discovered can be uniquely identified by this key. This is the key of all the built-in topic data types.

The value of element DDS_BUILTIN_TOPIC_KEY_OBJECT_ID is the object ID of the remote entity. In Dynamic Participant/Static Endpoint discovery, this must be set correctly for each remote DDSDataReader and DDSDataWriter that an application intends to discover.

For example, to configure a remote DDSDataWriter with object ID 100 by setting the key in the DDS_PublicationBuiltinTopicData:

 remote_pub_data.key.value[DDS_BUILTIN_TOPIC_KEY_OBJECT_ID]  = 100;
