Detailed Description

com.rti.dds.infrastructure.StatusKind.StatusKind.SUBSCRIPTION_MATCHED_STATUS

A "match" happens when the com.rti.dds.subscription.DataReader finds a com.rti.dds.publication.DataWriter for the same com.rti.dds.topic.Topic with an offered QoS that is compatible with that requested by the com.rti.dds.subscription.DataReader.

This status is also changed (and the listener, if any, called) when a match is ended. A local com.rti.dds.subscription.DataReader will become "unmatched" from a remote com.rti.dds.publication.DataWriter when that com.rti.dds.publication.DataWriter goes away for any reason.

Member Data Documentation

int total_count

The total cumulative number of times the concerned com.rti.dds.subscription.DataReader discovered a "match" with a com.rti.dds.publication.DataWriter.

This number increases whenever a new match is discovered. It does not change when an existing match goes away.

int total_count_change

The change in total_count since the last time the listener was called or the status was read.

int current_count

The current number of writers with which the com.rti.dds.subscription.DataReader is matched.

This number increases when a new match is discovered and decreases when an existing match goes away.

int current_count_peak

<<eXtension>> The highest value that current_count has reached until now.

int current_count_change

The change in current_count since the last time the listener was called or the status was read.

final InstanceHandle_t last_publication_handle

A handle to the last com.rti.dds.publication.DataWriter that caused the status to change.
