Examples of com.sun.xml.ws.rx.rm.runtime.sequence.Sequence.retrieveMessage()

com.sun.xml.ws.rx.rm.runtime.sequence.Sequence.retrieveMessage()

Retrieves a message stored within the sequence under the provided {@code correlationId}if avalable. May return {@code null} if no stored message under given {@code correlationId}is available.

Availability of the message depends on the message identifier acknowledgement. Message, if stored (see {@link #registerMessage(com.sun.xml.ws.rx.rm.runtime.ApplicationMessage,boolean)}remains available for retrieval until it is acknowledged. Once the message identifier associated with the stored message has been acknowledged, availability of the stored message is no longer guaranteed and stored message becomes eligible for garbage collection (if stored in memory) or removal.

Note however, that message MAY still be available even after it has been acknowledged. Thus it is NOT safe to use this method as a test of a message acknowledgement. @param correlationId correlation identifier of the stored {@link ApplicationMessage} @return the message that is stored in the sequence if available, {@code null} otherwise.
