Detailed Description

::DDS::StatusKind::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.

Member Data Documentation

System::Int32 DDS::PublicationMatchedStatus::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.

System::Int32 DDS::PublicationMatchedStatus::total_count_change

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

System::Int32 DDS::PublicationMatchedStatus::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.

System::Int32 DDS::PublicationMatchedStatus::current_count_peak

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

System::Int32 DDS::PublicationMatchedStatus::current_count_change

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

InstanceHandle_t DDS::PublicationMatchedStatus::last_subscription_handle

A handle to the last DDS::DataReader that caused the the DDS::DataWriter's status to change.
