copy

public static void copy(java.io.InputStream in,
                        java.io.OutputStream out,
                        boolean threaded,

                 throws java.io.IOException
Deprecated. maybe, use the version with a CopyThread as second parameter instead(I think it's cleaner, this version should go away).

This method copy the content of the InputStream in to the OutputStream out, in the calling thread or in a new one. If threaded is true, a new thread is created, and notify will be called at the end, and will have passed the exception eventually thrown while doing the copy. Otherwise, the copy is done synchronously; if an exception is thrown during the copy it is dispatched to the calling method, otherwise the notify is called.
