Method Detail

getInstance

public static final javax.servlet.http.HttpServletResponse getInstance(javax.servlet.http.HttpServletResponse response,
                                                                       Writer writer)

Returns a buffered response with a writer, if writer is not null; or the original response if writer is null. It is smart enough not to wrap the same writer twice.

Returns a buffered response with a output stream, if stream is not null; or the original response if stream is null. It is smart enough not to wrap the same stream twice.
