Detailed Description

DDS::Publisher entity and associated elements

DataWriterQos^ DDS::Publisher::DATAWRITER_QOS_DEFAULT [static, get, inherited]

Special value for creating DDS::DataWriter with default QoS.

When used in DDS::Publisher::create_datawriter, this special value is used to indicate that the DDS::DataWriter should be created with the default DDS::DataWriter QoS by means of the operation get_default_datawriter_qos and using the resulting QoS to create the DDS::DataWriter.

When used in DDS::Publisher::set_default_datawriter_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::Publisher::set_default_datawriter_qos operation had never been called.

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

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

DataWriterQos^ DDS::Publisher::DATAWRITER_QOS_USE_TOPIC_QOS [static, get, inherited]

Special value for creating DDS::DataWriter with a combination of the default DDS::DataWriterQos and the DDS::TopicQos.

The use of this value is equivalent to the application obtaining the default DDS::DataWriterQos and the DDS::TopicQos (by means of the operation DDS::Topic::get_qos) and then combining these two QoS using the operation DDS::Publisher::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::DataWriter.

This value should only be used in DDS::Publisher::create_datawriter.
