问题 I have a "getter" method like function getStuff($stuff){ return 'something'; } if I check it with empty($this->stuff) , I always get FALSE , but I know $this->stuff returns data, because it works with echo. and if I check it with !isset($this->stuff) I get the correct value and the condition is never executed... here's the test code: class FooBase{ public function __get($name){ $getter = 'get'.ucfirst($name); if(method_exists($this, $getter)) return $this->$getter(); throw new Exception(

问题 Assuming we have a class InnerClass with attributes and getter/setter. We also have a class OuterClass containing the InnerClass. e.g. class InnerClass { private int m_a; private int m_b; public int M_A { get { return m_a; } set { m_a = value; } } } class OuterClass { private InnerClass innerClass } How would I implement a correct getter and setter for the innerClass member of OuterClass? Thanks in advance! 回答1: The syntax wouldn't be any different. Just... public InnerClass InnerClass { get

问题 We have lambda expression for getter as below: Function<Student, String> studentNameGetter = Student::getName; How about lambda expression for the setter? 回答1: I'm not sure what you mean by creating a lambda expression for the setter. What it looks like you are trying to do is to assign the method reference to a suitable Functional Interface. In that case, the best match is to a BiConsumer: BiConsumer<Student, String> studentNameSetter = Student::setName; 来源： https://stackoverflow.com

问题 I'm new to Java, but have some OOP experience with ActionScript 3, so I'm trying to migrate relying on stuff I know. In ActionScript 3 you can create getters and setters using the get and set keywords, meaning you create a method in the class and access data through a property of an instance of that class. I might sound complicated, but it's not. Here's an example: class Dummy{ private var _name:String; public function Dummy(name:String=null){ this._name = name; } //getter public function get

问题 How can i access a static getter from an instance of the class that implements that getter? for example, i have this class: class Component { static get isComponent() { return true; } constructor() {} } const c = new Component(); how can i call from "c" "isComponent" of "Component" class? I read around and all I found is something like that: Object.getPrototypeOf(c).isComponent but this is not working on my case because there is no "isComponent" method in Component prototype object. The above
