Data Fields | |
DDS_Long | total_count |
The total cumulative number of times the concerned DDS_DataWriter discovered a "match" with a DDS_DataReader.This number increases whenever a new match is discovered. It does not change when an existing match goes away. | |
DDS_Long | total_count_change |
The incremental changes in total_count since the last time the listener was called or the status was read. | |
DDS_Long | current_count |
The current number of readers with which the DDS_DataWriter is matched.This number increases when a new match is discovered and decreases when an existing match goes away. | |
DDS_Long | current_count_change |
The change in current_count since the last time the listener was called or the status was read. | |
DDS_InstanceHandle_t | last_subscription_handle |
A handle to the last DDS_DataReader that caused the the DDS_DataWriter's status to change. |
<<cert>> DDS_PUBLICATION_MATCHED_STATUS
A "match" happens when the DDS_DataWriter finds a DDS_DataReader for the same DDS_Topic and common partition with a requested QoS that is compatible with that offered by the DDS_DataWriter.
This status is also changed (and the listener, if any, called) when a match is ended. A local DDS_DataWriter will become "unmatched" from a remote DDS_DataReader when that DDS_DataReader goes away for any reason.
