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.

Member Function Documentation

◆ get_type_name()

virtual const char* DDSTopicDescription::get_type_name ( )
pure virtual

Get the associated type_name.

The type name defines a locally unique type for the publication or the subscription.

The type_name corresponds to a unique string used to register a type via the FooTypeSupport::register_type method.

Thus, the type_name implies an association with a corresponding DDSTypeSupport and this DDSTopicDescription.

Returns
the type name. The returned type name is valid until the DDSTopicDescription is deleted.
Postcondition
The result is non-NULL.
