setter

In JavaScript there is the possibility to create getters and setters the following way: function MyClass(){ var MyField; this.__defineGetter__("MyField",function(){ return MyField; }); this.__defineSetter__("MyField",function(value){ MyField = value; }); } But is there a way to get the Getter or Setter FUNCTION? I think of something like this: var obj = new MyClass(); obj.__getSetter__("MyField")("MyValue"); I need such a functionality when extending base classes. For example: Class "A" has field "a", Class "B" extends from "A" and also wants to have a field "a". To pass values from the "a"

The following code runs for both var = putVar; & this.var = putVar; I understand: "this" is used to identify that - "put this value for just 'my' object". When both work, why do people usually use "this" in setters? code: public class PlayingWithObjects { public static void main(String[] args) { SomeClass classObj = new SomeClass(10); System.out.println("classObj.getVar: " + classObj.getVar() ); classObj.setVar(20); System.out.println("classObj.getVar: " + classObj.getVar() ); classObj = new SomeClass(30); System.out.println("classObj.getVar: " + classObj.getVar() ); } } class SomeClass {

I currently have a 2D array declared as: import Data.Array.Unboxed listArray ((0,0), (9,9)) (replicate 100 'f') ∷ UArray (Int, Int) Char I am trying to set a value in this array from a set of coordinates, (x, y) stored as a tuple, changing the value into a t , instead of an f . I have fooled around with lenses, however, I have had no success with them. Any help is appreciated! To access individual elements of an array with lens , you need to use the ix method of the Ixed class, defined in Control.Lens.At . If you define fooArray :: UArray (Int, Int) Char fooArray = listArray ((0,0), (9,9))

I have the following wrapper class: public class Wrapper { public int Member; } In a separate class, I have the following: public class ContainerClass { private Wrapper data; public Wrapper Property { get { return data; } set { data = value; } } public void Foo() { Property.Member = 42; } } When Property.Member is modified in Foo() , nothing happens (the setter is skipped). However, I can still do the following, for example: public void Foo() { Property = Property; } and enter the desired setter. So my question is, why doesn't modifying the member of an object property call that property's
