The change in total_count since the last time the listener was called or the status was read. | |
System::Int32 | current_count |
The current number of writers with which the DDS::DataReader is matched. | |
System::Int32 | current_count_peak |
<<extension>> The highest value that current_count has reached until now. | |
System::Int32 | current_count_change |
The change in current_count since the last time the listener was called or the status was read. | |
InstanceHandle_t | last_publication_handle |
A handle to the last DDS::DataWriter that caused the status to change. | |
::DDS::StatusKind::SUBSCRIPTION_MATCHED_STATUS
A "match" happens when the DDS::DataReader finds a DDS::DataWriter for the same DDS::Topic with an offered QoS that is compatible with that requested by the DDS::DataReader.
This status is also changed (and the listener, if any, called) when a match is ended. A local DDS::DataReader will become "unmatched" from a remote DDS::DataWriter when that DDS::DataWriter goes away for any reason.
System::Int32 DDS::SubscriptionMatchedStatus::total_count |
The total cumulative number of times the concerned DDS::DataReader discovered a "match" with a DDS::DataWriter.
This number increases whenever a new match is discovered. It does not change when an existing match goes away.
System::Int32 DDS::SubscriptionMatchedStatus::total_count_change |
The change in total_count since the last time the listener was called or the status was read.
System::Int32 DDS::SubscriptionMatchedStatus::current_count |
The current number of writers with which the DDS::DataReader is matched.
This number increases when a new match is discovered and decreases when an existing match goes away.
System::Int32 DDS::SubscriptionMatchedStatus::current_count_peak |
<<extension>> The highest value that current_count has reached until now.
System::Int32 DDS::SubscriptionMatchedStatus::current_count_change |
The change in current_count since the last time the listener was called or the status was read.
InstanceHandle_t DDS::SubscriptionMatchedStatus::last_publication_handle |
A handle to the last DDS::DataWriter that caused the status to change.
