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 com.rti.dds.infrastructure.RETCODE_INCONSISTENT_POLICY
