public abstract class WakeupCriterion
extends WakeupCondition

An abstract class specifying a singleton wakeup Criterion. This class consists of several subclasses, each of which specifies one particular wakeup criterion, that criterion's associated arguments (if any), and either a flag that indicates whether this criterion caused a Behavior object to awaken or a return field containing the information that caused the Behavior object to awaken.

Note that a unique WakeupCriterion object must be used with each instance of a Behavior. Sharing wakeup criteria among different instances of a Behavior is illegal. Similarly, a unique WakeupCriterion object must be used for each individual element in the set of arrays used to construct WakeupOr, WakeupAnd, WakeupOrOfAnds, and WakeupAndOfOrs objects.
