In my experience, most JS functions, constructor functions, or module-pattern functions, are declared as globals or are bound to a global namespace object. In any case, these identifiers are globally accessible. From any line of code in your system you can have: mod1 = somepackage.SomeModule(); // couple to me! Here's a quick JS exa...
I want to have an overloaded constructor where I change the value of the base class depending if the "isFirstPost" is set. If it's a first post, I want the rowkey = 000000. If it's not a first post, then make it a number. Don't really think of this as an Azure problem... but I'm more interested in the C# language and making a conditio...
In Clojure, given a class name as a string, I need to create a new instance of the class. In other words, how would I implement new-instance-from-class-name in (def my-class-name "org.myorg.pkg.Foo") ; calls constructor of org.myorg.pkg.Foo with arguments 1, 2 and 3 (new-instance-from-class-name my-class-name 1 2 3) I am looking fo...
This question is closely related to this one but i think is more general. Recently i try to create type "instances" on the fly with multimethods (or with a unique function constructor if possible), based in a metadata tag. I linked a type (a java class under the hood) with this tag and then i didnt know how to continue in a elegant way ...
hey I i am writing a Program in C++ and for some reason the compiler finds errors , and cant find my constructor: here is my class: (inside a h file) class Adjutancy { private: vector<Vehicale*,CompareCatId>* m_vehicalesVector; map<const string,Base*>* m_baseMap; map<const int,City*>* m_citiesMap; vector<vector<Distance*>>* m_distan...
Let's say that I have two classes A and B. class A { private: int value; public: A(int v) { value = v; } }; class B { private: A value; public: B() { // Here's my problem } } I guess it's something basic but I don't know how to ca...

suppose that MyClass has methods with the following prototypes: void method1(MyClass & object1); MyClass * method 7(); What will be this method destructor, constructor, copy constructor, overloaded= or default constructor? This is one of question in my homework. I think the first one is default constructor and second one is copy...
Hi. Consider the following class written in Java: class NonNegativeDouble { private final double value; public NonNegativeDouble(double value) { this.value = Math.abs(value); } public double getValue() { return value; } } It defines a final field called value that is initialized in the constructor, by taking i...
Hi, i was using object literal to create an object with methods. Here a simple example. var SizeManager = { width : 800, height : 600, ratio : this.width / this.height, resize : function (newWidth) { width = newWidth; height = newWidth / ratio; } } My issue is that SizeManager.ratio returns "NaN". ...
I'm working on implementing a Factory class along the lines of what is proposed in this response to a previous question: http://stackoverflow.com/questions/410823/factory-method-implementation-c/534396#534396 It's a Factory that stores a map from strings to object creation functions so I can request different types of objects from the ...
I'm a bit stuck on this SCJP practice question, specifically line 5 (with the String constructor). I thought it should be private, but the solution is 'protected'. I think protected access would not satisfy the requirement that all Alpha instances have the String alpha set to A. If the constructor is protected, then any other class that'...

Consider: struct A { A (int); A (const A &); }; struct B { A foo [2]; B (const A & x, const A & y) : foo {x, y} /* HERE IS THE PROBLEM */ {} }; I was expecting this to work since I'm using C++0x support in GCC4.3, which allegedly supports initialiser lists.
