• java.lang.Object
  • javax.servlet.ServletResponseWrapper
    • javax.servlet.http.HttpServletResponseWrapper

Fields Summary
protected HttpServletResponse	origResponse Original response
protected static final String	info Descriptive information about this Response implementation.
protected ServletOutputStream	stream The ServletOutputStream that has been returned by getOutputStream(), if any.
protected PrintWriter	writer The PrintWriter that has been returned by getWriter(), if any.
protected int	threshold The threshold number to compress
private int	debug Debug level
protected String	contentType Content type

Constructors Summary
public CompressionServletResponseWrapper(HttpServletResponse response) Calls the parent constructor which creates a ServletResponse adaptor wrapping the given response object. super(response); origResponse = response; if (debug > 1) { System.out.println("CompressionServletResponseWrapper constructor gets called"); }

Methods Summary
public javax.servlet.ServletOutputStream	createOutputStream() Create and return a ServletOutputStream to write the content associated with this Response. exception IOException if an input/output error occurs if (debug > 1) { System.out.println("createOutputStream gets called"); } CompressionResponseStream stream = new CompressionResponseStream(origResponse); stream.setDebugLevel(debug); stream.setBuffer(threshold); return stream;
public void	finishResponse() Finish a response. try { if (writer != null) { writer.close(); } else { if (stream != null) stream.close(); } } catch (IOException e) { }
public void	flushBuffer() Flush the buffer and commit this response. exception IOException if an input/output error occurs if (debug > 1) { System.out.println("flush buffer @ CompressionServletResponseWrapper"); } ((CompressionResponseStream)stream).flush();
public javax.servlet.ServletOutputStream	getOutputStream() Return the servlet output stream associated with this Response. exception IllegalStateException if getWriter has already been called for this response exception IOException if an input/output error occurs if (writer != null) throw new IllegalStateException("getWriter() has already been called for this response"); if (stream == null) stream = createOutputStream(); if (debug > 1) { System.out.println("stream is set to "+stream+" in getOutputStream"); } return (stream);
public java.io.PrintWriter	getWriter() Return the writer associated with this Response. exception IllegalStateException if getOutputStream has already been called for this response exception IOException if an input/output error occurs if (writer != null) return (writer); if (stream != null) throw new IllegalStateException("getOutputStream() has already been called for this response"); stream = createOutputStream(); if (debug > 1) { System.out.println("stream is set to "+stream+" in getWriter"); } //String charset = getCharsetFromContentType(contentType); String charEnc = origResponse.getCharacterEncoding(); if (debug > 1) { System.out.println("character encoding is " + charEnc); } // HttpServletResponse.getCharacterEncoding() shouldn't return null // according the spec, so feel free to remove that "if" if (charEnc != null) { writer = new PrintWriter(new OutputStreamWriter(stream, charEnc)); } else { writer = new PrintWriter(stream); } return (writer);
public void	setCompressionThreshold(int threshold) Set threshold number if (debug > 1) { System.out.println("setCompressionThreshold to " + threshold); } this.threshold = threshold;
public void	setContentLength(int length)
public void	setContentType(java.lang.String contentType) Set content type // --------------------------------------------------------- Public Methods if (debug > 1) { System.out.println("setContentType to "+contentType); } this.contentType = contentType; origResponse.setContentType(contentType);
public void	setDebugLevel(int debug) Set debug level this.debug = debug;
