<div class="block">Copies the contents of an InputStream to an OutputStream using a
copy buffer of a given size and notifies the provided
CopyStreamListener of the progress of the copy operation by calling
its bytesTransferred(long, int) method after each write to the

use a CopyStreamAdapter as the listener and register the additional
listeners with the CopyStreamAdapter.
<p>
The contents of the InputStream are
read until the end of the stream is reached, but neither the
source nor the destination are closed. You must do this yourself
outside of the method call. The number of bytes read/written is
returned.
