Description

Add API IOUtils.copy(InputStream, OutputStream, int)

    /**
     * Copy bytes from an <code>InputStream</code> to an <code>OutputStream</code> using an internal buffer of the
     * given size.
     * <p>
     * This method buffers the input internally, so there is no need to use a <code>BufferedInputStream</code>.
     * <p>
     * 
     * @param input
     *            the <code>InputStream</code> to read from
     * @param output
     *            the <code>OutputStream</code> to write to
     * @param bufferSize
     *            the bufferSize used to copy from the input to the output
     * @return the number of bytes copied
     * @throws NullPointerException
     *             if the input or output is null
     * @throws IOException
     *             if an I/O error occurs
     * @since 2.5
