getter-setter

one thing i've never really understood about AS3 is that you can't have a private set method and a public get method together. from within my class i would like to assign values that would call a private set function: myNumber = 22 ; but i need to pass that number as a parameter to a function myNumber(22); for example: package { //Imports import flash.display.Sprite //Class public class NumberClass extends Sprite { //Properties private var myNumberProperty:Number //Constructor public function NumberClass(myNumber:Number):void { this.myNumber = myNumber; init(); } //Initialize private function

I have alluded to this issue in my other question , but i think it's worthwhile breaking it out into its own question, as it's not really dependant on the other scenarios i mentioned. Anyways - onto the Q, don't know if this is possible. Looking for a solution/workaround. I have a Class Library, with nothing but POCO's: MyCompany.MyProject.Domain.POCO This assembly has a POCO like this: public class Post { public int PostId { get; set; } public int Name { get; set; } ... } Now, i have another Class Library, which is my DAL/Repository, and uses Entity Framework 4.0 for the persistence:

I want to create getter/setter methods dyanmically to retrieve private properties. This is what I did. First of all, I made the class: function winClass (posX, posY, w, h) { var x = posX || 0; var y = posY || 0; var width = w || 0; var height = h || 0; } Then I extended winClass with getter/setter methods, as follows: winClass.prototype.getX = function () { return x; } winClass.prototype.setX = function (val) { x = val; } And then I tested: var win1 = new winClass (10, 10, 100, 100); document.write (win1.getX ()); But the following error comes when I try to setup the 'getX' method: 'x is not

When using get in an object like this, get works: var people = { name: "Alex", get sayHi() { return `Hi, ${this.name}!` } }; var person = people; document.write(person.sayHi); But with a function I get an error. How to use Getters and Setters in a function like this? function People2() { this.name = "Mike"; get sayHi() { return `Hi, ${this.name}!`; } }; var user = new People2(); document.write(user.sayHi); You can use the actual get and set keywords only in classes (ES2015) and object literals. ECMAScript 5 In ES5, your would typically use Object.defineProperty to implement what you're trying

It is always recommended to use getter/setter for accessing private variables. Why would it not be a better idea to declare them as public and access them. Anyway we are accessing it using getter and setter? @mre answer is excellent and your question is fundamental. To summarize : you put the fields of an object private to gain control over the way it will be used by other objects. Your object uses setter to: restrict and validate data passed to the setter hide its inner data structure (other object are interested by a service not how the service is built, this can also include optimisation)

I have a few questions about getters and setters for arrays. Suppose we have a class like this, which makes a private copy of an array in its constructor: import java.util.Arrays; public class Foo { private int[] array; public Foo(int[] array) { this.array = Arrays.copyOf(array, array.length); } } We want the array to only be accessed/mutated via the getters and setters. If we have a getter that looks like this: public int[] getArray() { return array; } it defeats the purpose of the getter as we're returning a reference that allows the user to directly modify the elements of the array. e.g.
