Event & Subscription Datatypes

OcaEvent

struct OcaEvent

Representation of an OCA event, i.e. the unique combination of emitter ONo and the EventID.

OcaONo EmitterONo: Object number of the emitter.

OcaEventID EventID: Event ID of the subscribed event.

OcaMethod

struct OcaMethod

Representation of an OCA method, i.e. the unique combination of an ONo and a MethodID. To denote the absence of a method, all field values shall be zero. Such a value is called the Null Method Identifier.

OcaONo ONo: The object number. For Null Method Identifier, value shall be zero.

OcaMethodID MethodID: The method ID. For Null Method Identifier, value of all subfields shall be zero.

OcaNotificationDeliveryMode

enum OcaNotificationDeliveryMode : uint8_t

Enum for subscriptions that specifies whether its notification messages are to be delivered by normal means (e.g. TCP) or lightweight means (e.g. UDP).

enumerator Normal = 1: Normal delivery mode Name was ‘Reliable’ in AES70-2018 and earlier.

enumerator Lightweight = 2: Lightweight delivery mode. Name was ‘Fast’ in AES70-2018 and earlier.

OcaSubscriptionManagerState

enum OcaSubscriptionManagerState : uint8_t

Enum describing OcaSubscriptionManager states.

enumerator Normal = 1

enumerator EventsDisabled = 2: Events are disabled.
