Function Documentation

void cleanup ( )

inline

This will reclaim any resources allocated by the QosProvider.

DataReaderQos get_datareader_qos ( string  id )

inline

If 'id' is NULL, then the first instance of DataReaderQos in the library is returned. If 'id' is not NULL, then the 'name' field of the QoS policy is checked, and the first match is returned.

DataWriterQos get_datawriter_qos ( string  id )

inline

If 'id' is NULL, then the first instance of DataWriterQos in the library is returned. If 'id' is not NULL, then the 'name' field of the QoS policy is checked, and the first match is returned.

DomainParticipantQos get_participant_qos ( string  id )

inline

If 'id' is NULL, then the first instance of DomainParticipantQos in the library is returned. If 'id' is not NULL, then the 'name' field of the QoS policy is checked, and the first match is returned.

DomainParticipantFactoryQos get_participantfactory_qos ( string  id )

inline

If 'id' is NULL, then the first instance of DomainParticipantFactoryQos in the library is returned. If 'id' is not NULL, then the 'name' field of the DomainParticpantFactoryQos is checked, and the first match is returned.

PublisherQos get_publisher_qos ( string  id )

inline

If 'id' is NULL, then the first instance of PublisherQos in the library is returned. If 'id' is not NULL, then the 'name' field of the QoS policy is checked, and the first match is returned.

SubscriberQos get_subscriber_qos ( string  id )

inline

If 'id' is NULL, then the first instance of SubscriberQos in the library is returned. If 'id' is not NULL, then the 'name' field of the QoS policy is checked, and the first match is returned.

TopicQos get_topic_qos ( string  id )

inline

If 'id' is NULL, then the first instance of TopicQos in the library is returned. If 'id' is not NULL, then the 'name' field of the QoS policy is checked, and the first match is returned.

QosProvider ( string  uri, string  profile  )

inline

The QoS library source is indicated by 'uri'. Currently CoreDX DDS supports only the 'file:///' type URI. The QosProvider selects QoS policies from the library based on the 'profile' parameter.
