  /**
   * A client uses a <CODE>QueueReceiver</CODE> object to receive messages that
   * have been delivered to a queue. <p/>
   * <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/>
   * <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/>
   * <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.
