Detailed Description

DataReader expects a new sample updating the value of each instance at least once every deadline period.

DataWriter indicates that the application commits to write a new value (using the DataWriter) for each instance managed by the DataWriter at least once every deadline period.

period

fastdds::dds::Duration_t period

Maximum time expected between samples.

It is inconsistent for a DataReader to have a DEADLINE period less than its TimeBasedFilterQosPolicy minimum_separation.
By default, c_TimeInifinite.
