Counter Datatypes

OcaCounter

struct OcaCounter

A general-purpose Counter. See [AES70-1(Counters and Countersets)].

OcaID16 ID: Counter identifier. Unique within enclosing Counterset.

OcaUint64 Value: The count.

OcaUint64 InitialValue: Value that a reset sets in the Counter.

OcaString Role: Readonly name of Counter’s function in context. Values beginning with “oca” in any character case shall be reserved for AES use.

OcaList<OcaONo> Notifiers: List of ONos of Notifiers attached to this Counter. May be empty.

OcaCounterSet

struct OcaCounterSet

A set of Counters

OcaCounterSetID ID: Nonvolatile, unique identifier of this Counterset within this Device.

OcaList<OcaCounter> Counters: List of Counters in this Counterset.

OcaCounterSetID

using OcaCounterSetID = OcaBlob : Nonvolatile, unique identifier of a Counterset within a Device

OcaCounterNotifierFilterParameters

struct OcaCounterNotifierFilterParameters

Filter parameters for OcaCountersetNotifier.

OcaUint64 Threshold: Threshold comparison value. If Operator is zero, no threshold test is performed. See description of class OcaCounterNotifier.

OcaRelationalOperator Operator: Type of threshold comparison. See description of class OcaCounterNotifier.

OcaTimeInterval Period: Period for periodic updates, in seconds. Zero value means no periodic updates. See description of class OcaCounterNotifier.

OcaUint64 CountDelta: Count increment for “every-n-counts” updates. Absolute value, applies when counter changes by +n or -n. Zero value means no “every-n” notifications. See description of class OcaCounterNotifier.

OcaCounterUpdate

struct OcaCounterUpdate

Descriptor of a Counter update, used by OcaCounterNotifier, in its CounterUpdate() event and its GetLastUpdate() method.

OcaCounterSetID CounterSetID: Identifies Counterset within Device.

OcaID16 CounterID: Identifies Counter within Counterset.

OcaUint64 Value: The Counter’s value.
