Detailed Description

<<extension>> Describes the activity (i.e. are acknowledgements forthcoming) of reliable readers matched to a reliable writer.

This status is the reciprocal status to the com.rti.dds.subscription.LivelinessChangedStatus on the reader. It is different than the com.rti.dds.publication.LivelinessLostStatus on the writer in that the latter informs the writer about its own liveliness; this status informs the writer about the "liveliness" (activity) of its matched readers.

All counts in this status will remain at zero for best effort writers.
