javax.servlet Class ServletResponseWrapper

java.lang.Object
  extended by javax.servlet.ServletResponseWrapper
所有已实现的接口:
ServletResponse
直接已知子类:
HttpServletResponseWrapper
public class ServletResponseWrapper
extends Object
implements ServletResponse

Provides a convenient implementation of the ServletResponse interface that can be subclassed by developers wishing to adapt the response from a Servlet. This class implements the Wrapper or Decorator pattern. Methods default to calling through to the wrapped response object.
