35.1. Overview and Related Methods and Interfaces
A client uses a QueueBrowser object to look at messages on a queue without removing them.
The getEnumeration method returns a java.util.Enumeration that is used to scan the queue's messages. It may be an enumeration of the entire content of a queue, or it may contain only the messages matching a message selector.
Messages may be arriving and expiring while the scan is done. The JMS API does not require the content of an enumeration to be a static snapshot of queue content. Whether these changes are visible or not depends on the JMS provider.
The related methods and interfaces are
QueueSession.createBrowser(Queue)
QueueSession.createBrowser(Queue, String)
QueueReceiver
