Apache VFS supports file monitoring and monitoring.

The filelistener interface listens to three events:

• Filechanged (filechangeevent Eve): File Change, triggered only when filemonitor is used
• Filecreated (filechangeevent Eve): File Creation
• Filedeleted (filechangeevent Eve): deletes a file.

Filechangeevent is very simple. There is only one method GetFile () to return the fileobject object that triggers the event.
