Detailed Description

A std::bitset (list) of statuses.

The bit-mask is an efficient and compact representation of a fixed-length list of dds::core::status::StatusMask values.

Bits in the mask correspond to different statuses. You can choose which changes in status will trigger a callback by setting the corresponding status bits in this bit-mask and installing callbacks for each of those statuses.

The bits that are true indicate that the listener will be called back for changes in the corresponding status.

<<extension>> The number of unacknowledged samples in a reliable writer's cache has changed such that it has reached a pre-defined trigger point.

This status is considered changed at the following times: the cache is empty (i.e. contains no unacknowledge samples), full (i.e. the sample count has reached the value specified in dds::core::policy::ResourceLimits::max_samples), or the number of samples has reached a high (see rti::core::RtpsReliableWriterProtocol::high_watermark) or low (see rti::core::RtpsReliableWriterProtocol::low_watermark) watermark.

<<extension>> One or more reliable readers has become active or inactive.

A reliable reader is considered active by a reliable writer with which it is matched if that reader acknowledges the samples it has been sent in a timely fashion. For the definition of "timely" in this case, see rti::core::RtpsReliableWriterProtocol and rti::core::status::ReliableReaderActivityChangedStatus.
