SwitchedEnqueuePredicate

Class SwitchedEnqueuePredicate

public class SwitchedEnqueuePredicate extends Object implements EnqueuePredicate

The SwitchedEnqueuePredicate provides a mechanism where we can explicitly tell the queue whether we are accepting new events or not. This EnqueuePredicate is useful in situations where you have to set the accept status based on certain events. One example of where this is used is in the CommandManager code.
