类 FolderEvent

java.lang.Object

java.util.EventObject

javax.mail.event.MailEvent

javax.mail.event.FolderEvent

所有已实现的接口:

Serializable

public class FolderEvent
extends MailEvent

This class models Folder existence events. FolderEvents are delivered to FolderListeners registered on the affected Folder as well as the containing Store.

Service providers vary widely in their ability to notify clients of these events. At a minimum, service providers must notify listeners registered on the same Store or Folder object on which the operation occurs. Service providers may also notify listeners when changes are made through operations on other objects in the same virtual machine, or by other clients in the same or other hosts. Such notifications are not required and are typically not supported by mail protocols (including IMAP).
