The DataReaderListener provides asynchronous notification of DataReader events. This listener can be installed during DataReader creation, DomainParticipant_create_yyy(), as well as by calling DataReader_set_listener().
long get_nil_mask | ( | ) |
get_nil_mask() returns a bitmask indicating which listener methods (if any) should be considered NIL, and therefore, should not be invoked.
void on_data_available | ( | DataReader | the_reader | ) |
Called when the CoreDX DDS middleware detects that new data or data state information is available.
The status argument provides a snapshot of the status at the time the listener was invoked.
void on_liveliness_changed | ( | DataReader | the_reader, | |
LivelinessChangedStatus | status | |||
) |
Called when the CoreDX DDS middleware detects that the liveliness of a matched DataWriter has changed (either 'active' or 'inactive').
The status argument provides a snapshot of the status at the time the listener was invoked.
void on_requested_deadline_missed | ( | DataReader | the_reader, | |
RequestedDeadlineMissedStatus | status | |||
) | [package] |
Called when the CoreDX DDS middleware detects that the deadline specified in the DataReader QoS DEADLINE policy was not satisfied for a data instance.
The status argument provides a snapshot of the status at the time the listener was invoked.
void on_requested_incompatible_qos | ( | DataReader | the_reader, | |
RequestedIncompatibleQosStatus | status | |||
) |
Called when the CoreDX DDS middleware detects that the DataReader requested a QoS policy that was incompatible with that offered by a DataWriter.
The status argument provides a snapshot of the status at the time the listener was invoked.
void on_sample_lost | ( | DataReader | the_reader, | |
SampleLostStatus | status | |||
) |
Called when the CoreDX DDS middleware detects that a sample has been lost (never received).
The status argument provides a snapshot of the status at the time the listener was invoked.
void on_sample_rejected | ( | DataReader | the_reader, | |
SampleRejectedStatus | status | |||
) |
Called when the CoreDX DDS middleware detects that a sample has been rejected.
The status argument provides a snapshot of the status at the time the listener was invoked.
void on_subscription_matched | ( | DataReader | the_reader, | |
SubscriptionMatchedStatus | status | |||
) |
Called when the CoreDX DDS middleware detects that the DataReader has matched or ceased to be matched with a DataWriter.
The status argument provides a snapshot of the status at the time the listener was invoked.
