<<extension>> The status of a reader's internal protocol related metrics, like the number of samples received, filtered, rejected; and status of wire protocol traffic.
long received_sample_count |
The number of samples received by a DataReader.
Depending on how the com.rti.dds.subscription.DataReaderProtocolStatus was obtained this may count samples coming from a specific DataWriter or from all the DataWriters that are matched with the DataReader.
If the com.rti.dds.subscription.DataReaderProtocolStatus is obtained using the com.rti.dds.subscription.DataReader.get_datareader_protocol_status operation then it will count samples from any DataWriter. If the DataReaderProtocolStatus is obtained using the com.rti.dds.subscription.DataReader.get_matched_publication_datareader_protocol_status then it will count the samples for the DataWriter specified as a parameter to the function.
Duplicate samples arriving from the DataWriter(s) (e.g. via multiple network paths) are detected prior to increasing this counter. The duplicate samples are counted by com.rti.dds.subscription.DataReaderProtocolStatus.duplicate_sample_count.
If the DataReader has specified a ContentFilter the received samples that do not pass the filter are part of this counter. The filtered samples are counted by com.rti.dds.subscription.DataReaderProtocolStatus.filtered_sample_count.
Samples rejected because they do not fit on the DataReader Queue are also part of this counter.
Note the received_sample_count counts samples received from all DataWriters and it does not necessarily match the number of samples accepted into the DataReader Queue. This is because:
