Detailed Description

DDS::Subscriber entity and associated elements

Properties

DataReaderQos^ DDS::Subscriber::DATAREADER_QOS_DEFAULT
staticget

Special value for creating data reader with default QoS.

When used in DDS::Subscriber::create_datareader, this special value is used to indicate that the DDS::DataReader should be created with the default DDS::DataReader QoS by means of the operation get_default_datareader_qos and using the resulting QoS to create the DDS::DataReader.

When used in DDS::Subscriber::set_default_datareader_qos, this special value is used to indicate that the default QoS should be reset back to the initial value that would be used if the DDS::Subscriber::set_default_datareader_qos operation had never been called.

When used in DDS::DataReader::set_qos, this special value is used to indicate that the QoS of the DDS::DataReader should be changed to match the current default QoS set in the DDS::Subscriber that the DDS::DataReader belongs to.

Note: You cannot use this value to get the default QoS values for a DataReader; for this purpose, use DDS::DomainParticipant::get_default_datareader_qos.

DataReaderQos^ DDS::Subscriber::DATAREADER_QOS_USE_TOPIC_QOS
staticget

Special value for creating DDS::DataReader 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 DDS::Topic::get_qos) and then combining these two QoS using the operation DDS::Subscriber::copy_from_topic_qos whereby 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 DDS::DataReader.

This value should only be used in DDS::Subscriber::create_datareader.
