  javax.servlet.ServletResponseWrapper

All Implemented Interfaces:

ServletResponse

Direct Known Subclasses:

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. 提供了一种实现ServletResponse接口的便捷方式，开发人员想采用来自Servlet的响应的话， 可以对其子类化。该类实现了包装或装饰模式。方法默认调用经过包装的响应对象。
