Example 37 with ConsumerUID

use of com.sun.messaging.jmq.jmsserver.core.ConsumerUID in project openmq by eclipse-ee4j.

 * @param timeout The maximum time to wait (in milliseconds) for a message to be available before returning.<br>
 * Note that the method must return immediately if there is a message available for this consumerId at the time the call
 * is made.<br>
 * <UL>
 * <LI>When timeout is positive, the call must wait for a maximum of the specificied number of milliseconds before
 * returning. If a message is available before the timeout expires, the method returns with the message as soon as it is
 * available.</LI>
 * <LI>When timeout is 0, the call must block until a message is available to return or until the session is stopped.

 * <LI>When the timeout is negative (less than 0), the call must return immediately, with a message if one is available
 * or with a null, if a message is not available immediately.</LI>

 * @param acknowledge If this is set to {@code true} then it implies that the caller is asking for the message to be
 * <b>acknowledged</b> before the method returns. If this operation is part of a transaction, the {@code transactionId}
 * parameter will be non-zero.
