Member Function Documentation

long get_nil_mask

(

)

Returns a bitmask indicating which listener methods (if any) should be considered NIL, and therefore, should not be invoked.

void on_inconsistent_topic	(	Topic	the_topic,
		InconsistentTopicStatus	status
	)

Called when the CoreDX DDS middleware detects that another topic exists with different (inconsistent) characteristics.

The status argument provides a snapshot of the status at the time the listener was invoked.
