              org.omnifaces.servlet.BufferedHttpServletResponse

All Implemented Interfaces:

javax.servlet.http.HttpServletResponse, javax.servlet.ServletResponse

public class BufferedHttpServletResponse
extends HttpServletResponseOutputWrapper

This HTTP servlet response implementation buffers the entire response body. The buffered response body is available as a byte array via the getBuffer() method. Note that the buffered response writer will use same character encoding as is been set on the response supplied to the constructor and that this way any ServletResponse.setCharacterEncoding(String) calls on the included JSP/Servlet resource have thus no effect.
