All Implemented Interfaces:

public class MessageIterator
extends Object

An iterator over the Message objects within an Event

MessageIterator objects are used to process the individual Message objects in an Event received in an EventHandler, from EventQueue.nextEvent() or from AbstractSession.nextEvent(). This class is used to iterate over each message in an Event. You can use the MessageIterator as follows

     MessageIterator msgIter = event.messageIterator();
     while (msgIter.hasNext()) {
         Message msg = msgIter.next();
         ...
     }
