Member Data Documentation

DDS_LongLong DDS_DataWriterProtocolStatus::pushed_sample_count

The number of user samples pushed on write from a local DataWriter to a matching remote DataReader.

Counts protocol (RTPS) messages pushed by a DataWriter when writing, unregistering, and disposing. The count is the number of sends done internally, and it may be greater than the number of user writes.

For large data, counts whole samples, not fragments.

DDS_LongLong DDS_DataWriterProtocolStatus::pushed_sample_count_change

The incremental change in the number of user samples pushed on write from a local DataWriter to a matching remote DataReader since the last time the status was read.

Counts protocol (RTPS) messages pushed by a DataWriter when writing, unregistering, and disposing.

For large data, counts whole samples, not fragments.

DDS_LongLong DDS_DataWriterProtocolStatus::pushed_sample_bytes

The number of bytes of user samples pushed on write from a local DataWriter to a matching remote DataReader.

Counts bytes of protocol (RTPS) messages pushed by a DataWriter when writing, unregistering, and disposing. The count of bytes corresponds to the number of sends done internally, and it may be greater than the number of user writes.

For large data, counts bytes of whole samples, not fragments.

DDS_LongLong DDS_DataWriterProtocolStatus::pushed_sample_bytes_change

The incremental change in the number of bytes of user samples pushed on write from a local DataWriter to a matching remote DataReader since the last time the status was read.

Counts bytes of protocol (RTPS) messages pushed by a DataWriter when writing, unregistering, and disposing.

For large data, counts bytes of whole samples, not fragments.

DDS_LongLong DDS_DataWriterProtocolStatus::sent_heartbeat_count

The number of Heartbeats sent between a local DataWriter and matching remote DataReader.

Because periodic and piggyback heartbeats are sent to remote readers and their locators differently in different situations, when a reader has more than one locator, this count may be larger than expected, to reflect the sending of Heartbeats to the multiple locators.

DDS_LongLong DDS_DataWriterProtocolStatus::sent_heartbeat_count_change
