Writes <code>len</code> bytes from the specified
<code>byte</code> array starting at offset <code>off</code> to
this output stream.
<p>
The <code>write</code> method of <code>FilterOutputStream</code>
calls the <code>write</code> method of one argument on each
<code>byte</code> to output.
<p>
Note that this method does not call the <code>write</code> method
of its underlying output stream with the same arguments. Subclasses
of <code>FilterOutputStream</code> should provide a more efficient
implementation of this method.
@param b the data.
@param off the start offset in the data.
@param len the number of bytes to write.
@exception IOException if an I/O error occurs.
