Detailed Description

QoS policies supported by a com.rti.dds.publication.DataWriter entity.

You must set certain members in a consistent manner:

- com.rti.dds.publication.DataWriterQos.history.depth <= com.rti.dds.publication.DataWriterQos.resource_limits.max_samples_per_instance

- com.rti.dds.publication.DataWriterQos.resource_limits.max_samples_per_instance <= com.rti.dds.publication.DataWriterQos.resource_limits.max_samples

- com.rti.dds.publication.DataWriterQos.resource_limits.initial_samples <= com.rti.dds.publication.DataWriterQos.resource_limits.max_samples

- com.rti.dds.publication.DataWriterQos.resource_limits.initial_instances <= com.rti.dds.publication.DataWriterQos.resource_limits.max_instances

- length of com.rti.dds.publication.DataWriterQos.user_data.value <= com.rti.dds.domain.DomainParticipantQos.resource_limits .writer_user_data_max_length

If any of the above are not true, com.rti.dds.publication.DataWriter.set_qos and com.rti.dds.publication.DataWriter.set_qos_with_profile and com.rti.dds.publication.Publisher.set_default_datawriter_qos and com.rti.dds.publication.Publisher.set_default_datawriter_qos_with_profile will fail with RETCODE_INCONSISTENT_POLICY and com.rti.dds.publication.Publisher.create_datawriter and com.rti.dds.publication.Publisher.create_datawriter_with_profile and will return NULL.

Entity:

com.rti.dds.publication.DataWriter
