getter-setter

Context: I have a company model with many projects , having many tasks . The company also has many employees , which in turn have many tasks . Schema: Problem: I'm building a form to create a project where the user can add multiple tasks . Upon submission the form should create a single project record, one or more task records with hours and employee_id attributes and (!) check if the employee name already exists in the database or create a new one. I've approached this by adding jquery autocomplete to the form and defining a virtual attribute with a getter and setter method in my Task model.

I've searched a lot for how to do properties in Javascript. Most all of the revealing module pattern I've seen has exclusively exposed functions, and from experience I know if I expose an object, I'm only really getting a copy of the value right there and then, thus simply I could have a function getMyThing() and setMyThing and expose that. However I'm wanting to expose real properties I've seen the oldschool defineGetter which I'm avoiding and the newer Object.defineProperty( which I had some real troubles with. (I could easily use it against an artitary object but not THIS inside my "module"

This question already has answers here : Closed 7 years ago . Possible Duplicate: Why use getters and setters? Can anyone tell me what is the use of getter/setter method? In one of the interview someone asked me to write a simple class...so, I wrote the class as shown below: class X { int i; public: void set(int ii){ i = ii;} int get(){ return i;} }; Now, The question goes like this: Q1. Why did you declare the variable 'i' as private and not as public? My answer: Bcoz, data is always sensitive and by declaring it private you'll prevent it from being exposed to the outside world. To counter my

Help me understand data Binding When I create a variable in a class: [Bindable] private var _name:String; and then generate getters and setters, I get: private var _name:String; [Bindable] public function get name():String { return _name; } public function set name(value:String):void { _name = value; } Why does it generate the tag '[Bindable]' only on the get function? To me, it would seem that it should be on the set function, as I would want to know when the value changes, not when the value is just read. What might help to understand what is going on here is the code that the MXML compiler

I am trying to solve a problem that came to my mind lately. Let's say we would want and would know how to make a point in having dynamic getters and setters in javascript, more like those in php (__get, __set). But as javascript does not have a catch-all property the only thing we could do is to provide a list of possible keys and iterate to add getters and setters on those only, and hope none other will ever come. But the problem is not by far solved. So the next approach that came to my mind was to use a nasty hack with try and catch , so anytime a name would be undefined in an object to use

Consider the following class: class MyClass1 { public: double x() const {return _x;} // getter double y() const {return _y;} // getter double z() const {return _x*_y;} // getter void x(const double var) {_x = var;} // setter void y(const double var) {_y = var;} // setter void z(const double var) {_x = var; _y = 1;} // setter protected: double _x; double _y; }; As the actual contents of MyClass1 is an implementation detail, the getters and setters provide a unified way to get and set the class contents even if they are interdependant (here _z does not exists internally but for the user, z is a
