Detailed Description

QoS policies supported by a DDS::Topic entity.

You must set certain members in a consistent manner:

length of DDS::TopicQos::topic_data .value <= DDS::DomainParticipantQos::resource_limits .topic_data_max_length

If any of the above are not true, DDS::Topic::set_qos, DDS::Topic::set_qos_with_profile and DDS::DomainParticipant::set_default_topic_qos will fail with DDS::Retcode_InconsistentPolicy and DDS::DomainParticipant::create_topic will return NULL.

Entity:

DDS::Topic
