/** A <CODE>Queue</CODE> object encapsulates a provider-specific queue name. 
  * It is the way a client specifies the identity of a queue to JMS API methods.
  * For those methods that use a <CODE>Destination</CODE> as a parameter, a 
  * <CODE>Queue</CODE> object used as an argument. For example, a queue can
  * be used  to create a <CODE>MessageConsumer</CODE> and a 
  * <CODE>MessageProducer</CODE>  by calling:
  *<UL>
  *<LI> <CODE>Session.CreateConsumer(Destination destination)</CODE>
  *<LI> <CODE>Session.CreateProducer(Destination destination)</CODE>
  *
  *</UL>
  *
  * <P>The actual length of time messages are held by a queue and the 
  * consequences of resource overflow are not defined by the JMS API.
