DeadlineQosPolicy Struct Reference

Data Fields
Duration_t	period

Detailed Description

This QoS policy establishes a minimum update period for data instances.

DataWriters specify that each data instance will be updated at least once every 'period'. A DataReader requests that the Writer commit to updating each instance at least once every 'period'.

The policy is compatible (between a Writer and a Reader) if the offered deadline period <= requested deadline period.

If a DataWriter fails to meet the update period, then the DataWriter is notified by a call to the offered_deadline_missed listener, and the DataReader is notified by a call to the requested_deadlin_missed listener.
