创建具有不同目标对象的方法引用列表？ [英] create a list of method references with different target object?

问题描述

我仍在消化Java 8中的lambda概念。现在，需要在我的服务中创建一个方法引用列表，该服务中还有2个其他服务对象。这就是需要发生的事情

I am still digesting the lambda conception in Java 8. Now it comes to a need of create a list of method references in my service, which has 2 other services objects. This is what needs to happen

Person person = new Person();
this.method1(person);
service2.method2(person);
service3.method3(person);

因此列表应具有

0 -> this.method1,
1 -> service2.method2,
2 -> service3.method3,

非常重要的是，没有新的this.class，service2或service3实例是创建。不确定实现该目标的最佳方法。我可以帮忙吗？

It is very important that no new instances of this.class, service2 or service3 is created. Not sure the best way to achieve that. Can I have some help?

推荐答案

您似乎只想要

List<Consumer<Person>> list = Arrays.asList(
    this::method1, service2::method2, service3::method3);
for (Consumer<Person> action : list) {
  action.accept(person);
}
