Member Data Documentation

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.

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.

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.

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

The number of user samples preemptively filtered by a local DataWriter due to Content-Filtered Topics.

The incremental change in the number of user samples preemptively filtered by a local DataWriter due to Content-Filtered Topics since the last time the status was read.

The number of user samples preemptively filtered by a local DataWriter due to Content-Filtered Topics.

The incremental change in the number of user samples preemptively filtered by a local DataWriter due to Content-Filtered Topics since the last time the status was read.

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.

The incremental change in the number of Heartbeats sent between a local DataWriter and matching remote DataReader since the last time the status was read.

Pulled samples are samples sent for repairs, for late joiners, and all samples sent by the local DataWriter when DDS::DataWriterProtocolQosPolicy::push_on_write is false.

For large data, counts whole samples, not fragments.
