类 ResponsibilityChain<T>

java.lang.Object

net.lulihu.designPattern.chain.AbstractHandlerResponsibilityChainResolver<T>

net.lulihu.designPattern.chain.ResponsibilityChain<T>

所有已实现的接口:

HandlerResponsibilityChainResolver<T>

public abstract class ResponsibilityChain<T>
extends AbstractHandlerResponsibilityChainResolver<T>

建议责任链的形式化实现

使用方式代码如下:

 public static class A extends ResponsibilityChain {
  public boolean support(AtomicInteger data) {
   return true;
 }

  public boolean resolve(AtomicInteger data) {
   System.out.println(data.intValue());
   data.incrementAndGet();
   return true;
  }
 }

 public static void main(String[] args) {
  ResponsibilityChain chain = new A();
  chain.addHandler(new A()).addHandler(new A());
  chain.handler(new AtomicInteger(1));
 }
 

注意：因为是以每个处理程序包含着下个处理程序的指针形成的责任模式，所有请使用第一个处理对象调用 handler方法
