setter

I know that private instance variables are accessed through their public getters and setters method. But when I generate constructors with the help of IDE, it initializes instance variables directly instead of initializing them through their setter methods. Q1. So should I change the IDE generated code for constructors to initialize those instance variables through their setter methods. Q2. If yes, then why IDE don't generate constructors code in that way? ============================= EDITED ======================================= I use Eclipse and Netbeans IDE It's a general question. But as

While working with Node.js, Mongoose and MongoDB, I have found that my Mongoose schema getters and setters do not fire when I perform a findOne query. I have found an old thread that suggests there was an issue with getters and setters in version 2.x, but it states that it has since been resolved and I'm using the very latest version of Mongoose (3.8.7). Here's part of my schema function testGetter(value) { return value + " test"; } /** * Schema */ var schema = new Schema({ username: { type: String, required: true, unique: true, get: testGetter } }); // I have also tried this. schema.path(

I've read a few articles/posts regarding the use of Getters and Setters, and how they help to defeat the purpose of encapsulation in domain model objects. I understand the logic behind not using setters - you are allowing client code to manipulate attributes of that object, outside the context of the object business rules and invariants. Now this principal does still confuse me. For example, what happens if I need to change the value of a member variable of an object? For example, if the name of a person changes how can I reflect this in the model? At first I thought, well why not have a

I am trying to get getter/setter support for ng-model by implementing a directive that will take care of getting and setting the values to/from the view/model. I am almost there, but I end up in infinite $digest loops. The idea is to set ng-model="$someFieldToStoreInTheScope", and then have the getter/setter directive do the updates between that field and the getter/setter functions. I use $watch to update the model using the setter expression when the ngModelController updates the field in the scope, and another watch to update that field when the getter expression changes. Have a look at:

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! The syntax wouldn't be any different. Just... public InnerClass InnerClass { get { return innerClass; } set { innerClass = value; } } By the way, if you're using C# in .NET 3.5, you can use

I have a base class with a property which has a setter method. Is there a way to invoke the setter in the base class from a derived class and add some more functionality to it just like we do with overriden methods using the base keyword. Sorry I should have added an example. Here is an example. Hope I get it right: public class A { public abstract void AProperty { set { // doing something here } } } public class B : A { public override void AProperty { set { // how to invoke the base class setter here // then add some more stuff here } } } EDIT : the revised example should demostrate the

Summary Code sample: Class People { // private property. private $name; // other methods not shown for simplicity. } Straight forward. Let me assume that $name is a PRIVATE class member (or property, variable, field, call it as you wish) . Is there any way to do these in PHP: $someone = new People(); $someone->name = $value; $somevar = $someone->name; WITHOUT using __get($name) and __set($name, $value) . Background I needed to check the assigned $value , therefore I simply need a getter setter like this: getName(); setName($value); And NOT necessarily a getter setter magic method overloading

I'm trying to make an API as user friendly as possible. Let's have: class B extends A {} class A { A setX(){ ...; return this; } } Now this B b = new B().setX(); is invalid, has to be casted: B b = (B) new B().setX(); Is there a way using generics in A to make compiler aware of "this" type and accept the first way - without casting and without passing type parameter at the place where used? (I.e. not new B<B>().setX() , that's ugly.) I KNOW why Java needs retyping in this case. Please no answers explaing that setX() returns A. I know that. I am asking if generics can solve this. And for those
