Detailed Description

SERVICE_REQUEST_ACCEPTED_STATUS.

Currently, the only service that causes the ServiceRequestAcceptedStatus to be triggered is the DDS::TopicQuery service. A DDS::ServiceRequest is accepted when a DDS::DataWriter matches with a DDS::DataReader that has created a DDS::TopicQuery.

This status is also changed (and the listener, if any, called) when a ServiceRequest has been cancelled, or deleted. This will happen when a DDS::DataReader deletes a TopicQuery using DDS::DataReader::delete_topic_query.

The incremental changes in total_count since the last time the listener was called or the status was read.

System::Int32 DDS::ServiceRequestAcceptedStatus::current_count

The current number of ServiceRequests that have been accepted by this DDS::DataWriter.

This number increases when a new request is accepted and decreases when an existing request is cancelled.

System::Int32 DDS::ServiceRequestAcceptedStatus::current_count_change

The change in current_count since the last time the listener was called or the status was read.

InstanceHandle_t DDS::ServiceRequestAcceptedStatus::last_request_handle
