Method Detail

getOutputStream

public final javax.servlet.ServletOutputStream getOutputStream()
                                                        throws IOException

Throws:

IOException

getWriter

public final PrintWriter getWriter()
                            throws IOException

Throws:

IOException

createOutputStream

protected OutputStream createOutputStream()
                                   throws IOException

Returns the OutputStream. Subclasses should override this method to provide a decorated output stream. This method is guaranteed to be invoked only once for a request/response (unless resetBuffer is invoked).

This implementation simply returns the output stream from the wrapped response.

Returns:

the OutputStream to use for the response

Throws:

IOException - if an I/O exception occurs

flushBuffer

public void flushBuffer()
                 throws IOException

Throws:

IOException

resetBuffer

public void resetBuffer()
