Method Detail

getInstance

public static final javax.servlet.ServletResponse getInstance(javax.servlet.ServletResponse response,
                                                              java.io.Writer writer)
Returns a buffered response with a writer, if writer is not null; or the original response if writer is null. If reponse is HttpServletResponse, HttpBufferedResponse.getInstance(javax.servlet.http.HttpServletResponse, java.io.Writer) is returned. It is smart enough not to wrap the same writer twice.


getInstance

public static final javax.servlet.ServletResponse getInstance(javax.servlet.ServletResponse response,
                                                              java.io.OutputStream stream)
Returns a buffered response with a output stream, if stream is not null; or the original response if stream is null. If reponse is HttpServletResponse, HttpBufferedResponse.getInstance(javax.servlet.http.HttpServletResponse, java.io.Writer) is returned. It is smart enough not to wrap the same stream twice.
