It also forces newlines to allways be \r\n.

Method Detail

setWriter

public void setWriter(javax.servlet.ServletOutputStream stream,
                      java.lang.String encoding)
               throws java.io.IOException

clearBuffer

public void clearBuffer()

getRemaining

public int getRemaining()

Returns:

the remaining data in the buffer -- does not account for ServletResponse.getBufferSize

getEncoding

public java.lang.String getEncoding()

close

public void close()

appear to be closed, w/out actually closing the underlying writer. just flush it and release it, which gives the appearance of being closed. PrintWriter is forgiving when you call close() multiple times. but ServletOutputStream is not.
