Class DirectoryMonitor

java.lang.Object
  org.apache.geronimo.deployment.hot.DirectoryMonitor

All Implemented Interfaces:

Runnable

public class DirectoryMonitor
extends Object
implements Runnable

Meant to be run as a Thread that tracks the contents of a directory. It sends notifications for changes to its immediate children (it will look into subdirs for changes, but will not send notifications for files within subdirectories). If a file continues to change on every pass, this will wait until it stabilizes before sending an add or update notification (to handle slow uploads, etc.).
