DDS.Entity subtypes are created and destroyed by factory objects. With the exception of DDS.DomainParticipant, whose factory is DDS.DomainParticipantFactory, all DDS.Entity factory objects are themselves DDS.Entity subtypes as well.
Important: all DDS.Entity delete operations are inherently thread-unsafe. The user must take extreme care that a given DDS.Entity is not destroyed in one thread while being used concurrently (including being deleted concurrently) in another thread. An operation's effect in the presence of the concurrent deletion of the operation's target DDS.Entity is undefined.
