javax.mail.event
Class MessageCountEvent

java.lang.Object
 extended by java.util.EventObject
 extended by javax.mail.event.MailEvent
 extended by javax.mail.event.MessageCountEvent

All Implemented Interfaces:: java.io.Serializable

public class MessageCountEvent
extends MailEvent
extends MailEvent

This class notifies changes in the number of messages in a folder.

Note that some folder types may only deliver MessageCountEvents at certain times or after certain operations. IMAP in particular will only notify the client of MessageCountEvents when a client issues a new command. Refer to RFC 2060 http://www.ietf.org/rfc/rfc2060.txt for details. A client may want "poll" the folder by occasionally calling the getMessageCount or isConnected methods to solicit any such notifications.
