Detailed Description

QoS policies supported by a DDS::DataWriter entity.

You must set certain members in a consistent manner:

- DDS::DataWriterQos::history.depth <= DDS::DataWriterQos::resource_limits.max_samples_per_instance

- DDS::DataWriterQos::resource_limits.max_samples_per_instance <= DDS::DataWriterQos::resource_limits.max_samples

- DDS::DataWriterQos::resource_limits.initial_samples <= DDS::DataWriterQos::resource_limits.max_samples

- DDS::DataWriterQos::resource_limits.initial_instances <= DDS::DataWriterQos::resource_limits.max_instances

- length of DDS::DataWriterQos::user_data.value <= DDS::DomainParticipantQos::resource_limits .writer_user_data_max_length

If any of the above are not true, DDS::DataWriter::set_qos and DDS::DataWriter::set_qos_with_profile and DDS::Publisher::set_default_datawriter_qos and DDS::Publisher::set_default_datawriter_qos_with_profile will fail with DDS::Retcode_InconsistentPolicy and DDS::Publisher::create_datawriter and DDS::Publisher::create_datawriter_with_profile and will return NULL.

<<eXtension>> Transport plugin selection policy, TRANSPORT_SELECTION.

Specifies the transports available for use by the DDS::DataWriter.

<<eXtension>> Unicast transport policy, TRANSPORT_UNICAST.

The unicast interfaces are used to receive messages from DDS::DataReader entities in the domain.

<<eXtension>> Publish mode policy, PUBLISH_MODE.

Determines whether the DDS::DataWriter publishes data synchronously or asynchronously and how.

<<eXtension>> Property policy, PROPERTY.

<<eXtension>> Batch policy, BATCH.

<<eXtension>> Multi channel policy, MULTICHANNEL.

<<eXtension>> Type support data, TYPESUPPORT.

Optional value that is passed to a type plugin's on_endpoint_attached and serialization functions.
