Class HttpServletResponseSwitch

java.lang.Object

javax.servlet.ServletResponseWrapper

javax.servlet.http.HttpServletResponseWrapper

org.apache.myfaces.shared.view.HttpServletResponseSwitch

All Implemented Interfaces:

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

public class HttpServletResponseSwitch
extends javax.servlet.http.HttpServletResponseWrapper
implements ResponseSwitch

Implementation of a switching response wrapper to turn output on and off according to the JSF spec 2.0.

Implemented as HttpServletResponseWrapper, so that the switching does not interfere with methods that expect a HttpServletResponse when invoking ExternalContext.getResponse().
