class TimeBasedFilterQosPolicy : public eprosima::fastdds::dds::Parameter_t, public eprosima::fastdds::dds::QosPolicy

Filter that allows a DataReader to specify that it is interested only in (potentially) a subset of the values of the data. The filter states that the DataReader does not want to receive more than one value each minimum_separation, regardless of how fast the changes occur. It is inconsistent for a DataReader to have a minimum_separation longer than its Deadline period.


Mutable Qos Policy


This QosPolicy can be defined and is transmitted to the rest of the network but is not implemented in this version.

Public Functions
