Detailed Description

QoS policies supported by a com.rti.dds.subscription.DataReader entity.

You must set certain members in a consistent manner:

com.rti.dds.subscription.DataReaderQos.deadline.period >= com.rti.dds.subscription.DataReaderQos.time_based_filter.minimum_separation

com.rti.dds.subscription.DataReaderQos.history.depth <= com.rti.dds.subscription.DataReaderQos.resource_limits.max_samples_per_instance

com.rti.dds.subscription.DataReaderQos.resource_limits.max_samples_per_instance <= com.rti.dds.subscription.DataReaderQos.resource_limits.max_samples com.rti.dds.subscription.DataReaderQos.resource_limits.initial_samples <= com.rti.dds.subscription.DataReaderQos.resource_limits.max_samples

com.rti.dds.subscription.DataReaderQos.resource_limits.initial_instances <= com.rti.dds.subscription.DataReaderQos.resource_limits.max_instances

com.rti.dds.subscription.DataReaderQos.reader_resource_limits.initial_remote_writers_per_instance <= com.rti.dds.subscription.DataReaderQos.reader_resource_limits.max_remote_writers_per_instance

com.rti.dds.subscription.DataReaderQos.reader_resource_limits.initial_infos <= com.rti.dds.subscription.DataReaderQos.reader_resource_limits.max_infos

com.rti.dds.subscription.DataReaderQos.reader_resource_limits.max_remote_writers_per_instance <= com.rti.dds.subscription.DataReaderQos.reader_resource_limits.max_remote_writers

com.rti.dds.subscription.DataReaderQos.reader_resource_limits.max_samples_per_remote_writer <= com.rti.dds.subscription.DataReaderQos.resource_limits.max_samples

length of com.rti.dds.subscription.DataReaderQos.user_data.value <= com.rti.dds.domain.DomainParticipantQos.resource_limits.reader_user_data_max_length

If any of the above are not true, com.rti.dds.subscription.DataReader.set_qos and com.rti.dds.subscription.DataReader.set_qos_with_profile will fail with RETCODE_INCONSISTENT_POLICY
