Class PrintWriterServletOutputStream

java.lang.Object
  java.io.OutputStream
      javax.servlet.ServletOutputStream
          org.apache.portals.gems.util.PrintWriterServletOutputStream

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable

public class PrintWriterServletOutputStream
extends javax.servlet.ServletOutputStream

This is a specialized class implementing a ServletOutputStream that works in conjunction with a PrintWriter to send data to the browser. It is used when a J2EE server throws an IllegalStateException when you call getOutputStream on a response which someone has previously called getWriter on.

Constructor Summary

PrintWriterServletOutputStream(java.io.PrintWriter pO)
Deprecated. since 1.0RC3; use PrintWriterServletOutputStream

Construct a ServletOutputStream that coordinates output using a base ServletOutputStream and a PrintWriter that is wrapped on top of that OutputStream.

PrintWriterServletOutputStream(java.io.PrintWriter pw, java.lang.String encoding)

Method Summary

void	close() Closes the stream
void	flush() Flushes the stream, writing any buffered output bytes
void	print(java.lang.String pVal) Prints a string.
void	println() Prints a CRLF
void	println(java.lang.String pVal) Prints an string followed by a CRLF.
void	write(byte[] pBuf) Writes an array of bytes
void	write(byte[] pBuf, int pOffset, int pLength) Writes a subarray of bytes This implementation redirects it's input into the underlying PrintWriter.
void	write(int pVal) Writes a single byte to the output stream This implementation writes the byte to the underlying PrintWriter.
