Detailed Description

Field Documentation

struct DDS_Listener DDS_DataWriterListener::as_listener

The superclass instance of this DDS_DataWriterListener.

DDS_DataWriterListener_OfferedDeadlineMissedCallback DDS_DataWriterListener::on_offered_deadline_missed

Handles the DDS_OFFERED_DEADLINE_MISSED_STATUS status.

This callback is called when the deadline that the DDS_DataWriter has committed through its DEADLINE qos policy was not respected for a specific instance. This callback is called for each deadline period elapsed during which the DDS_DataWriter failed to provide data for an instance.

DDS_DataWriterListener_OfferedIncompatibleQosCallback DDS_DataWriterListener::on_offered_incompatible_qos

Handles the DDS_OFFERED_INCOMPATIBLE_QOS_STATUS status.

This callback is called when the DDS_DataWriterQos of the DDS_DataWriter was incompatible with what was requested by a DDS_DataReader. This callback is called when a DDS_DataWriter has discovered a DDS_DataReader for the same DDS_Topic and common partition, but with a requested QoS that is incompatible with that offered by the DDS_DataWriter.

DDS_DataWriterListener_LivelinessLostCallback DDS_DataWriterListener::on_liveliness_lost

Handles the DDS_LIVELINESS_LOST_STATUS status.

This callback is called when the liveliness that the DDS_DataWriter has committed through its LIVELINESS qos policy was not respected; this DDS_DataReader entities will consider the DDS_DataWriter as no longer "alive/active". This callback will not be called when an already not alive DDS_DataWriter simply renames not alive for another liveliness period.

DDS_DataWriterListener_PublicationMatchedCallback DDS_DataWriterListener::on_publication_matched

Handles the DDS_PUBLICATION_MATCHED_STATUS status.

This callback is called when the DDS_DataWriter has found a DDS_DataReader that matches the DDS_Topic, has a common partition and compatible QoS, or has ceased to be matched with a DDS_DataReader that was previously considered to be matched.

DDS_DataWriterListener_ReliableWriterCacheChangedCallback DDS_DataWriterListener::on_reliable_writer_cache_changed

<<eXtension>> A change has occurred in the writer's cache of unacknowledged samples.

This listener callback is triggered when:

DDS_DataWriterListener_ReliableReaderActivityChangedCallback DDS_DataWriterListener::on_reliable_reader_activity_changed

<<eXtension>> A matched reliable reader has become active or become inactive.

DDS_DataWriterListener_InstanceReplacedCallback DDS_DataWriterListener::on_instance_replaced

Notifies when an instance is replaced in DataWriter queue.

This callback is called when an instance is replaced by the DDS_DataWriter due to instance resource limits being reached. This callback returns to the user the handle of the replaced instance, which can be used to get the key of the replaced instance.
