java.lang.Object | +--com.ibm.mqe.jms.MQeQueueBrowser
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.

QueueBrowser
.
Since a provider may allocate some resources on behalf of a QueueBrowser outside the Java virtual machine, clients should close them when they are not needed. Relying on garbage collection to eventually reclaim these resources may not be timely enough.
