 * A {@code Queue} object encapsulates a provider-specific queue name.
 *
 * 
 * It is the way a client specifies the identity of a queue to Jakarta Messaging API methods. For those methods that use a
 * {@code Destination} as a parameter, a {@code Queue} object used as an argument. For example, a queue can be used to
 * create a {@code MessageConsumer} and a {@code MessageProducer} by calling:
 *
 * 

 * {@code Session.CreateConsumer(Destination destination)}
 * 
{@code Session.CreateProducer(Destination destination)}
 * 
 *
 * 
 * The actual length of time messages are held by a queue and the consequences of resource overflow are not defined by
 * the Jakarta Messaging API.
