| JspWriterImpl(javax.servlet.ServletResponse response)Create a buffered character-output stream that uses a default-sized
 output buffer. | 
| JspWriterImpl(javax.servlet.ServletResponse response,
             int sz,
             boolean autoFlush)Create a new buffered character-output stream that uses an output
 buffer of the given size. |

 Ordinarily this method stores characters from the given array into
 this stream's buffer, flushing the buffer to the underlying stream as
 needed.  If the requested length is at least as large as the buffer,
 however, then this method will flush the buffer and write the characters
 directly to the underlying stream.  Thus redundant
 DiscardableBufferedWriters will not copy data unnecessarily.
