/**
 * 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.
