public interface TopicDescription<TYPE>
extends DDSObject

This interface is the base for Topic, ContentFilteredTopic, and MultiTopic. TopicDescription represents the fact that both publications and subscriptions are tied to a single data type. Its attribute typeName defines a unique resulting type for the publication or the subscription and therefore creates an implicit association with a TypeSupport. TopicDescription has also a name that allows it to be retrieved locally.
