Class SingleMessageBox<V>

java.lang.Object
  threadExamples.SingleMessageBox<V>

Type Parameters:

V - The type of "message" that may be put into this SingleMessageBox.

public class SingleMessageBox<V>
extends java.lang.Object

Implements a message box which can hold only a single message at a time. Behavior is almost identical to that of BatonMessageBox, but the implementation is different: the put and get methods are themselves synchronized, rather than using a separate object on which to synchronize.
