Detailed Description
<<interface>> Base class for DDS::Topic, DDS::ContentFilteredTopic, and DDS::MultiTopic.
ITopicDescription 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 DDS::TypeSupport.
ITopicDescription has also a name that allows it to be retrieved locally.

◆ get_type_name()
| System::String ^ DDS::ITopicDescription::get_type_name | ( | ) |
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 DDS::TypeSupport and this ITopicDescription.
- Returns
- the type name. The returned type name is valid until the ITopicDescription is deleted.
- Postcondition
- The result is non-NULL.
