> The official php client includes a Facebook object (and a
> FacebookDesktop object as well). This object uses FacebookRestClient,
> but it also exposes a wealth of useful functionality which is sorely
> missing from the current Java client.
> I am writing a feature-by-feature Java implementation of this object,
> and I would like to know if there is any interest by the developers
> and users of this group to include it in the next version of this
> project. Including this object will not break the drop-in
> compatibility, of course.

> Features provided by this object:

> 1) Verifying that the various fb_sig_ parameters are authentic, using
> md5 hashing with the app's secret key. I think this is an important
> security feature. Facebook expects apps to do this, and with the php
> client it happens automatically.

> 2) Easy to use methods for login and authentication.
> Facebook.require_login() to force login, Facebook.require_add() to
> force the user to add the application, Facebook.require_frame() to
> force the app to be inside a facebook frame (as opposed to a stand-
> alone webapp).

> 3) The above mentioned methods use a smart redirect feature. It emits
> an fmbl redirect code if the page is in a canvas, or sends a "frame-
> bypassing" redirect if using an iframe (so you don't nest duplicate
> facebook navigation bars), or simply sends a redirect if the app is a
> stand-alone webapp).

> 3) Additional useful methods, such as Facebook.is_fb_canvas(),
> Facebook.is_frame() to determine if the app is in a frame or canvas.

> 4) Fall-back to using cookies for authentication if the fb_sig_ params
> are not present (I haven't implemented this yet).

> Please let me know if this would be useful for this project.
