PropertyChangeListener

public abstract class LocalGENASubscription
extends GENASubscription<LocalService>
implements PropertyChangeListener

An incoming subscription to a local service.

Uses the ServiceManager to read the initial state of the LocalService on instantation. Typically, the registerOnService() method is called next, and from this point forward all ServiceManager.EVENTED_STATE_VARIABLES property change events are detected by this subscription. After moderation of state variable values (frequency and range of changes), the GENASubscription.eventReceived() method is called. Delivery of the event message to the subscriber is not part of this class, but the implementor of GENASubscription.eventReceived().

moderateStateVariables

protected Set<String> moderateStateVariables(long currentTime,
 Collection<StateVariableValue> values)

Checks whether a state variable is moderated, and if this change is within the maximum rate and range limits.

Parameter:

currentTime - The current unix time.

values - The state variable values to moderate.

Gibt zurück:

A collection of state variable values that although they might have changed, are excluded from the event.

incrementSequence

public void incrementSequence()

setSubscriptionDuration

public void setSubscriptionDuration(Integer requestedDurationSeconds)

Parameter:

requestedDurationSeconds - If null defaults to UserConstants.DEFAULT_SUBSCRIPTION_DURATION_SECONDS

ended

public abstract void ended(CancelReason reason)
