Detailed Description

<<interface>> Base class for DDSTopic, DDSContentFilteredTopic, and DDSMultiTopic.

DDSTopicDescription represents the fact that both publications and subscriptions are tied to a single data-type. Its attribute type_name defines a unique resulting type for the publication or the subscription and therefore creates an implicit association with a DDSTypeSupport.

DDSTopicDescription has also a name that allows it to be retrieved locally.
