If the requested length is at least as large as this stream's 0N/A * buffer, however, then this method will flush the buffer and write the 0N/A * bytes directly to the underlying output stream. Thus redundant 0N/A * <code>BufferedOutputStream</code>s will not copy data unnecessarily. 0N/A * @param b the data. 0N/A * @param off the start offset in the data. 0N/A * @param len the number of bytes to write. 0N/A * @exception IOException if an I/O error occurs. 0N/A /* If the request length exceeds the size of the output buffer, 0N/A flush the output buffer and then write the data directly. 0N/A In this way buffered streams will cascade harmlessly. */ 0N/A * Flushes this buffered output stream. This forces any buffered 0N/A * output bytes to be written out to the underlying output stream. 0N/A * @exception IOException if an I/O error occurs. 0N/A * @see java.io.FilterOutputStream#out
