java.lang.Object

javax.servlet.ServletResponseWrapper

javax.servlet.http.HttpServletResponseWrapper

grails.plugin.cache.web.GenericResponseWrapper

All Implemented Interfaces:

java.io.Serializable, javax.servlet.http.HttpServletResponse, javax.servlet.ServletResponse

public class GenericResponseWrapper
extends javax.servlet.http.HttpServletResponseWrapper
implements java.io.Serializable

Provides a wrapper for HttpServletResponseWrapper.

It is used to wrap the real Response so that we can modify it after that the target of the request has delivered its response.

It uses the Wrapper pattern.

Based on net.sf.ehcache.constructs.web.GenericResponseWrapper.
