All Implemented Interfaces:

Monitor, java.lang.Runnable

public class DirectoryFileStateMonitor

extends AbstractFileStateMonitor

Like a FileStateMonitor, but monitors a specifig directory, rather than a specific collection of files. Why? We want to allow for new files being created. @TODO we're going to need to allow filters though.
