JFileWatch

JFileWatch tries to provide a single api to filesystem events for various operating systems. It uses JNI to interact with the os api. In case of Linux I'd say its a rather complete implementation now.

The "move event" still has some limitations where I think it has something to do with limitations of inotify itself, have to have a look at it. Currently do not expect that the "move event" works in any other case than a simple "rename file" operation.

Installation

See included README.txt for installation instructions.

Changelog

• 1-2 2006-Sep-03: Support recursive watch of directories. Support MOVE_SELF event. Some bugfixes e.g. update internal datastructures in case of "moved files" and unwatch/remove events. Changed API to use java.io.File instead of String.
• 1.1 2006-Sep-02: upgrade to kernel 2.6.16 (and maybe older ... dont know)
• 1.0 2005-May-08: birthday

Example

The following example will recursively watch a directory.

        FileWatch fw = FileWatchFactory.create();
        fw.addWatch(new File("/home/im/tmp"), true);
        fw.addListener(new FileWatchEventListener()
        {
            public void processFileWatchEvent(FileWatchEvent evt)
            {
                System.err.println(evt);
            }
        });

You could attach multiple watches and listeners to a single fileWatch instance.

Currently supported OS

• linux with inotify enabled kernel (inotify is part of the kernel now)
• inotify home: http://www.ibm.com/developerworks/linux/library/l-inotify.html

TODO

Volunteers wanted!!

• support windows
• support mac
