Class Enactor

java.lang.Object
  context.arch.enactor.Enactor

Direct Known Subclasses:

InstallationEnactor, LightEnactor, PresenceEnactor, TemperatureEnactor, VisitorDisplayEnactor

public abstract class Enactor

extends java.lang.Object

The Enactor component encapsulates application logic and simplifies the acquisition of context data. Use it by making subclasses that define their own EnactorReferences and EnactorParameters. To be useful, an Enactor should have an EnactorSubscriptionManager set upon it.
