  nl.knowledgeplaza.util.DirectoryMonitor

public class DirectoryMonitor
extends java.lang.Object

Nested Class Summary

static interface	DirectoryMonitor.AddListener listen to new files // client side myDirectoryMonitor.addListeners.add(new DirectoryMonitor.AddListener(){ @Override public void add(File file) { }});
static interface	DirectoryMonitor.ChangeListener listen to any change // client side myDirectoryMonitor.changeListeners.add(new DirectoryMonitor.ChangeListener(){ @Override public void changed(File file) { }});
static interface	DirectoryMonitor.DeleteListener listen to removed files // client side myDirectoryMonitor.deleteListeners.add(new DirectoryMonitor.DeleteListener(){ @Override public void deleted(File file) { }});

Field Summary

ListenerHandler<DirectoryMonitor.AddListener,java.io.File>	addListeners

Constructor Summary

DirectoryMonitor()
We use a fluent interface, so use the withXXX methods and end with start();
