getter-setter

“Forward-unbreakable” accessor class templates [C++]

由 好久不见. 提交于 2020-01-12 10:44:09
问题 Unless I am thoroughly mistaken, the getter/setter pattern is a common pattern used for two things: To make a private variable so that it can be used, but never modified, by only providing a getVariable method (or, more rarely, only modifiable, by only providing a setVariable method). To make sure that, in the future, if you happen to have a problem to which a good solution would be simply to treat the variable before it goes in and/or out of the class, you can treat the variable by using an

问题 I am using Thread for Webservice but i cant get the data from Thread because i cant return data from Thread .

Why does 1 of these getter/setters work and the others don't

问题 I have a class which has 2 sets of getter & setters. 1 set is the traditional type. These work as expected: var userEmail : String { get { return UserDefaults.standard.string(forKey: UserDefaultKeys.profileEmail) ?? "" } set (newValue) { UserDefaults.standard.set(newValue, forKey: UserDefaultKeys.profileEmail) UserDefaults.standard.synchronize() } } var podSerialNum : Int { get { return UserDefaults.standard.integer(forKey: UserDefaultKeys.profilePodSN) } set (newValue) { UserDefaults

Javascript: Mixing in a getter (object spread)

由 一笑奈何 提交于 2020-01-04 14:11:32
问题 I tried creating mixing in a getter into a JS object via the spread operator syntax, however it always seems to return null . HTML: <body> <div id="wrapperA"></div> <div id="wrapperB"></div> </body> <script src='./test.js'></script> JS: "use strict"; const mixin = { get wrapper() { return document.getElementById(this.wrappername); } } const wrapperA = { wrappername: 'wrapperA', ...mixin } const wrapperB = { wrappername: 'wrapperB', ...mixin } console.log(wrapperA); console.log(wrapperB);

Object.prototype.__defineGetter__ (and __defineSetter__) polyfill

由 南楼画角 提交于 2020-01-04 06:23:12
问题 I know the __defineGetter__ (and __defineSetter__ ) method name is really weird and deprecated but I find it more convenient than Object.defineProperty . Compare yourself: //Readable Something.prototype.__defineGetter__("name", function() {return this._name;}); //Uh... - what? Object.defineProperty(Something.prototype, "name", { get: function() {return this._name;} }); Because, as I said, this method is being deprecated. So I'm creating a polyfill to put it back in bussiness: if(!Object

How to remove the setter from a JavaScript object?

由 你说的曾经没有我的故事 提交于 2020-01-04 03:32:26
问题 Consider the following code: var x = 0; var o = {}; function getter() { return x; } Object.defineProperty(o, "y", { get: getter, set: function (y) { x = y; Object.defineProperty(o, "y", { get: getter }); }, configurable: true }); My objective is to remove the setter and make the property o.y non-configurable after the setter has been called once. However it doesn't work as expected: > x // 0 > o.y // 0 > o.y = 1 // 1 > x // 1 > o.y // 1 > o.y = 2 // 2 > x // 2 > o.y // 2 So my code did not

C# Getter/Setter problem

由 北战南征 提交于 2020-01-04 02:53:32
问题 Say i have a property in a class: Vector3 position{get; set;} So i create an instance of that class somewhere and now i want to change position.x, that would be impossible now because the getter and setter set and get the whole object. So i have to make a temporary Vector3 change its values and then assign it. Normally i would make position a public field so that problem would be solved. But i cant do it in this case because position is an implementation of an interface and interfaces cant

__call catches static method calls

问题 I'm using both the magic methods _call and _callStatic for my own implementation of something like an ORM/Activerow. They're mainly meant for catching certain function calls: __call is responsible for getters and setters, and __callStatic for findBy methods (e.g. findById ). To map foreign keys, i'm trying to convert calls to e.g. getArticle to return the value of Article::findById() . To do that, i'm using this case inside my __call : if (strstr($property, "_id")) { return $foreignClass:
