Topic is the basic description of data to be published or subscribed. A topic is identified by a name and a type. A Topic is created by calling DomainParticipant.create_topic(). Prior to creating a Topic, the associated data type must be registered with the DomainParticipant via a call to the TypeSupportXYZ.register_type() function. [The register_type() function is auto-generated 'type-specific' code.]

Enables the Topic. A Topic is created either enabled or not based on the DomainParticipantQos setting entity_factory. When a Topic is not enabled, only the following sub-set of all Topic operations are legal:
Any other operation may return the ReturnCode_t.RETURNCODE_NOT_ENABLED error. Topic.enable() may be called on an already enabled Topic [it will have no effect].
Reimplemented from Entity.

Provides access to the InconsistentTopicStatus of the Topic. As a side-effect, this routine will reset the total_count_change status field to zero.

Installs a TopicListener on Topic t. Only one listener may be attached to a Topic at a time. A call to set_listener() will replace any current listener with a_listener.
a_listener can be NULL, which indicates a listener that does nothing.
The infrastructure will make an internal copy of the listener structure so that it need not be persisted by the application.

Sets the TopicQos values. These QoS values affect the behavior of the Topic. This routine may fail if the provided qos argument is not internally consistent. In this case, ReturnCode_t.RETCODE_INCONSISTENT_POLICY will be returned, and no changes will be made to the Topic QoS.
