The DDS_SubscriberListener provides asynchronous notification of DDS_Subscriber events.
This listener can be installed during Subscriber creation, DDS_DomainParticipant_create_subscriber() as well as by calling DDS_Subscriber_set_listener().
void(* DDS_SubscriberListener::on_data_available)(DDS_DataReader the_reader) |
on_data_available() is called when the CoreDX DDS middleware detects that a DataReader contained in the Subscriber has new data or data state information available. This listener is invoked only if the concerned DDS_DataReader does not have an on_data_available listener installed.
The status argument provides a snapshot of the status at the time the listener was invoked.
void(* DDS_SubscriberListener::on_data_on_readers)(DDS_Subscriber the_subscriber) |
on_data_on_readers() is called when the CoreDX DDS middleware detects that data or data state information arrives at any DataReader contained within the Subscriber.
The status argument provides a snapshot of the status at the time the listener was invoked.
void(* DDS_SubscriberListener::on_liveliness_changed)(DDS_DataReader the_reader, DDS_LivelinessChangedStatus status) |
on_liveliness_changed() is called when the CoreDX DDS middleware detects that the liveliness of a DataWriter, matched to a DataReader within this Subscriber, has changed (either 'active' or 'inactive'). This listener is invoked only if the concerned DDS_DataReader does not have an on_liveliness_changed listener installed.
The status argument provides a snapshot of the status at the time the listener was invoked.
void(* DDS_SubscriberListener::on_requested_deadline_missed)(DDS_DataReader the_reader, DDS_RequestedDeadlineMissedStatus status) |
on_requested_deadline_missed() is called when the CoreDX DDS middleware detects that the QoS DEADLINE policy of a DataReader, contained in this Subscriber, was not satisfied for a data instance. This listener is invoked only if the concerned DDS_DataReader does not have an on_requested_deadline_missed listener installed.
The status argument provides a snapshot of the status at the time the listener was invoked.
void(* DDS_SubscriberListener::on_requested_incompatible_qos)(DDS_DataReader the_reader, DDS_RequestedIncompatibleQosStatus status) |
on_requested_incompatible_qos() is called when the CoreDX DDS middleware detects that a DataReader contained in the Subscriber has requested a QoS policy that was incompatible with that offered by a DataWriter. This listener is invoked only if the concerned DDS_DataReader does not have an on_requested_incompatible_qos listener installed.
The status argument provides a snapshot of the status at the time the listener was invoked.
void(* DDS_SubscriberListener::on_sample_lost)(DDS_DataReader the_reader, DDS_SampleLostStatus status) |
on_sample_lost() is called when the CoreDX DDS middleware detects that a DataReader contained in the Subscriber has lost a sample (never received). This listener is invoked only if the concerned DDS_DataReader does not have an on_sample_lost listener installed.
The status argument provides a snapshot of the status at the time the listener was invoked.
void(* DDS_SubscriberListener::on_sample_rejected)(DDS_DataReader the_reader, DDS_SampleRejectedStatus status) |
on_sample_rejected() is called when the CoreDX DDS middleware detects that a DataReader contained in the Subscriber has rejected a sample. This listener is invoked only if the concerned DDS_DataReader does not have an on_sample_rejected listener installed.
The status argument provides a snapshot of the status at the time the listener was invoked.
void(* DDS_SubscriberListener::on_subscription_matched)(DDS_DataReader the_reader, DDS_SubscriptionMatchedStatus status) |
on_subscription_matched() is called when the CoreDX DDS middleware detects that a DataReader contained in the Subscriber has matched or ceased to be matched with a DataWriter. This listener is invoked only if the concerned DDS_DataReader does not have an on_subscription_matched listener installed.
The status argument provides a snapshot of the status at the time the listener was invoked.
