The DDS_DomainParticipantListener_cd provides asynchronous notification of DDS_DomainParticipant events with additional callback data arguments.
This listener can be installed by calling DDS_DomainParticipant_set_listener_cd().
| void(* DDS_DomainParticipantListener_cd::on_data_available) (struct DDS_DomainParticipantListener_cd *self, DDS_DataReader the_reader, void *callback_data) |
on_data_available() is called when the CoreDX DDS middleware detects that a DataReader, contained in any Subscriber in this DomainParticipant, has new data or data state information available. This listener is invoked only if the concerned DDS_DataReader and DDS_Subscriber do 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_DomainParticipantListener_cd::on_data_on_readers) (struct DDS_DomainParticipantListener_cd *self, DDS_Subscriber the_subscriber, void *callback_data) |
on_data_on_readers() is called when the CoreDX DDS middleware detects that a DataReader, contained in any Subscriber in this DomainParticipant, has new data or data state information available. This listener is invoked only if the concerned DDS_Subscriber does not have an on_data_on_readers listener installed.
The status argument provides a snapshot of the status at the time the listener was invoked.
| void(* DDS_DomainParticipantListener_cd::on_inconsistent_topic) (struct DDS_DomainParticipantListener_cd *self, DDS_Topic the_topic, DDS_InconsistentTopicStatus status, void *callback_data) |
on_inconsistent_topic() is called when the CoreDX DDS middleware detects that a Topic contained within this DomainParticipant has characteristics taht are different (inconsistent) with another existing topic. This listener is invoked only if the concerned DDS_Topic does not have an on_inconsistent_topic listener installed.
The status argument provides a snapshot of the status at the time the listener was invoked.
| void(* DDS_DomainParticipantListener_cd::on_liveliness_changed) (struct DDS_DomainParticipantListener_cd *self, DDS_DataReader the_reader, DDS_LivelinessChangedStatus status, void *callback_data) |
on_liveliness_changed() is called when the CoreDX DDS middleware detects that the liveliness of a DataWriter, matched to a DataReader within any Subscriber within this DomainParticipant, has changed (either 'active' or 'inactive'). This listener is invoked only if the concerned DDS_DataReader and DDS_Subscriber do 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_DomainParticipantListener_cd::on_liveliness_lost) (struct DDS_DomainParticipantListener_cd *self, DDS_DataWriter writer, DDS_LivelinessLostStatus status, void *callback_data) |
on_liveliness_lost() is called when the CoreDX DDS middleware detects that a DataWriter contained in any Publisher within this DomainParticipant has not satisfied its LIVELINESS QoS setting. This listener is invoked only if the concerned DDS_DataWriter and DDS_Publisher do not have an on_liveliness_lost listener installed.
The status argument provides a snapshot of the status at the time the listener was invoked.
| void(* DDS_DomainParticipantListener_cd::on_offered_deadline_missed) (struct DDS_DomainParticipantListener_cd *self, DDS_DataWriter writer, DDS_OfferedDeadlineMissedStatus status, void *callback_data) |
on_offered_deadline_missed() is called when the CoreDX DDS middleware detects that a DataWriter contained in any Publisher within this DomainParticipant has failed to meet its DEADLINE QoS commitment. This listener is invoked only if the concerned DDS_DataWriter and DDS_Publisher do not have an on_offered_deadline_missed listener installed.
The status argument provides a snapshot of the status at the time the listener was invoked.
| void(* DDS_DomainParticipantListener_cd::on_offered_incompatible_qos) (struct DDS_DomainParticipantListener_cd *self, DDS_DataWriter writer, DDS_OfferedIncompatibleQosStatus status, void *callback_data) |
on_offered_incompatible_qos() is called when the CoreDX DDS middleware detects that a DataWriter contained in any Publisher within this DomainParticipant has offered a QoS policy setting that is incompatible with that requested by a potentially matching DataReader. This listener is invoked only if the concerned DDS_DataWriter and DDS_Publisher do not have an on_offered_incompatible_qos listener installed.
The status argument provides a snapshot of the status at the time the listener was invoked.
| void(* DDS_DomainParticipantListener_cd::on_publication_matched) (struct DDS_DomainParticipantListener_cd *self, DDS_DataWriter writer, DDS_PublicationMatchedStatus status, void *callback_data) |
on_publication_matched() is called when the CoreDX DDS middleware detects that a DataWriter contained in any Publisher within this DomainParticipant has matched with a DataReader or has ceased to be matched with a DataReader. This listener is invoked only if the concerned DDS_DataWriter and DDS_Publisher do not have an on_publication_matched listener installed.
The status argument provides a snapshot of the status at the time the listener was invoked.
| void(* DDS_DomainParticipantListener_cd::on_requested_deadline_missed) (struct DDS_DomainParticipantListener_cd *self, DDS_DataReader the_reader, DDS_RequestedDeadlineMissedStatus status, void *callback_data) |
on_requested_deadline_missed() is called when the CoreDX DDS middleware detects that the QoS DEADLINE policy of a DataReader, contained in any Subscriber of this DomainParticipant, was not satisfied for a data instance. This listener is invoked only if the concerned DDS_DataReader and DDS_Subscriber do 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_DomainParticipantListener_cd::on_requested_incompatible_qos) (struct DDS_DomainParticipantListener_cd *self, DDS_DataReader the_reader, DDS_RequestedIncompatibleQosStatus status, void *callback_data) |
on_requested_incompatible_qos() is called when the CoreDX DDS middleware detects that a DataReader contained in any Subscriber within this DomainParticipant, has requested a QoS policy that was incompatible with that offered by a DataWriter. This listener is invoked only if the concerned DDS_DataReader and DDS_Subscriber do 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_DomainParticipantListener_cd::on_sample_lost) (struct DDS_DomainParticipantListener_cd *self, DDS_DataReader the_reader, DDS_SampleLostStatus status, void *callback_data) |
on_sample_lost() is called when the CoreDX DDS middleware detects that a DataReader, contained in any Subscriber in this DomainParticipant, has lost a sample (never received). This listener is invoked only if the concerned DDS_DataReader and DDS_Subscriber do 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_DomainParticipantListener_cd::on_sample_rejected) (struct DDS_DomainParticipantListener_cd *self, DDS_DataReader the_reader, DDS_SampleRejectedStatus status, void *callback_data) |
on_sample_rejected() is called when the CoreDX DDS middleware detects that a DataReader contained in any Subscriber within the DomainParticipan has rejected a sample. This listener is invoked only if the concerned DDS_DataReader and DDS_Subscriber do 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_DomainParticipantListener_cd::on_subscription_matched) (struct DDS_DomainParticipantListener_cd *self, DDS_DataReader the_reader, DDS_SubscriptionMatchedStatus status, void *callback_data) |
on_subscription_matched() is called when the CoreDX DDS middleware detects that a DataReader, contained in any Subscriber in this DomainParticipant, has matched or ceased to be matched with a DataWriter. This listener is invoked only if the concerned DDS_DataReader and DDS_Subscriber do not have an on_subscription_matched listener installed.
The status argument provides a snapshot of the status at the time the listener was invoked.
