类 ResponsibilityChainHandler<T>

java.lang.Object

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

类型参数:

T -

public class ResponsibilityChainHandler<T>
extends Object

责任链处理程序

使用方式代码如下:

 public static class B extends AbstractHandlerResponsibilityChainResolver {

  public boolean support(AtomicInteger data) {
   return true;
  }

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

  public static void main(String[] args) {
   ResponsibilityChainHandler chainHandler = new ResponsibilityChainHandler<>();
   chainHandler.addHandler(new B()).addHandler(new B()).addHandler(new B());
   chainHandler.handler(new AtomicInteger(1));
   }
