DDSSubscriber entity and associated elements
struct DDS_DataReaderQos DDS_DATAREADER_QOS_DEFAULT |
<<cert>> Special value for creating data reader with default QoS.
When used in DDSSubscriber::create_datareader, this special value is used to indicate that the DDSDataReader should be created with the default DDSDataReader QoS.
struct DDS_DataReaderQos DDS_DATAREADER_QOS_USE_TOPIC_QOS |
Special value for creating DDSDataReader with a combination of the default DDS_DataReaderQos and the DDS_TopicQos.
The use of this value is equivalent to the application obtaining the default DDS_DataReaderQos and the DDS_TopicQos (by means of the operation DDSTopic::get_qos) and then combining these two QoS so that any policy that is set on the DDS_TopicQos "overrides" the corresponding policy on the default QoS. The resulting QoS is then applied to the creation of the DDSDataReader.
This value should only be used in DDSSubscriber::create_datareader.
