/** A client uses a <CODE>QueueReceiver</CODE> object to receive messages that
* have been delivered to a queue.
*
* <P>Although it is possible to have multiple <CODE>QueueReceiver</CODE>s
* for the same queue, the JMS API does not define how messages are
* distributed between the <CODE>QueueReceiver</CODE>s.
*
* <P>If a <CODE>QueueReceiver</CODE> specifies a message selector, the
* messages that are not selected remain on the queue. By definition, a message
* selector allows a <CODE>QueueReceiver</CODE> to skip messages. This
* means that when the skipped messages are eventually read, the total ordering
* of the reads does not retain the partial order defined by each message
* producer. Only <CODE>QueueReceiver</CODE>s without a message selector
* will read messages in message producer order.
*
* <P>Creating a <CODE>MessageConsumer</CODE> provides the same features as
* creating a <CODE>QueueReceiver</CODE>. A <CODE>MessageConsumer</CODE> object is
* recommended for creating new code. The <CODE>QueueReceiver</CODE> is
* provided to support existing code.
