Please see an example of my code below: CODE UPDATED public class ScrollableCheckboxList { public List<ScrollableCheckboxItem> listitems; public ScrollableCheckboxList<TModel>(IEnumerable<TModel> items, string valueField, string textField, string titleField) where TModel : class { listitems = new List<ScrollableChe...
I have a class "Artikel" and there i write some Business Logic. I also have a class "tArtikel" which is a type. In my class "Artikel" I work with "tArtikel" and returns are of that type. Now when i instantiate an "Artikel" i want it to be of type "tArtikel", so what i tried in my code is: public tArtikel Artikel() { ...
Recently read in a article on dotnetpearls.com here saying that static ctors take a substantial amount of perfomance hit. Could not fathom why ? ...
In my domain I have a handful of "processor" classes which hold the bulk of the business logic. Using StructureMap with default conventions, I inject repositories into those classes for their various IO (databases, file system, etc.). For example: public interface IHelloWorldProcessor { string HelloWorld(); } public class HelloWor...
HI, I have create my iPhone apps but i have a problem. I have a classViewController where i have implemented my program. I must alloc 3 NSMutableArray but i don't want do it in a grapich methods. There isn't a constructor like java for my class? Thanks so much and sorry for my english XP // I want put it in a method like constructor jav...
I've found this strange behavior with VS2005 C++ compiler. Here is the situation: I cannot publish the code, but situation is very simple. Here is initial code: it work perfectly class Foo { public: Foo(Bar &bar) { ... } } The constructor implementation stores a reference, setup some members... indeed nothing special. If ...
Hello, I have some class(Window) without copy constructor (it's private). I can't understand how to init var of this class in my own class: class MyClass { Window obj; // Hasn't copy constructor public: void init() { obj = Window(/* constructor params */); // [error] obj(/* constructor params */); // ...
I attempted to use public function __construct() { } but got the error ErrorException [ Strict ]: Creating default object from empty value. The reason behind this is that I use a controller that is protected for logged in users only, I don't want to have to call $this->protect(); from every action in the controller. Hence my a...
What I want to do: run some prerequisite code whenever instance of the class is going to be used inside a program. This code will check for requiremts etc. and should be run only once. I found that this can be achieved using another object as static variable inside a constructor. Here's an example for a better picture: class Prerequisi...
I'm getting back to programming for Google App Engine and I've found, in old, unused code, instances in which I wrote constructors for models. It seems like a good idea, but there's no mention of it online and I can't test to see if it works. Here's a contrived example, with no error-checking, etc.: class Dog(db.Model): name = db....
What is the effect of a return statement in the body of JavaScript function when it's used as a constructor for a new object(with 'new' keyword)? ...
I'm working on a simple framework, and I'm having a slight problem. I'd like to use call_user_function_array() to pass parameters to a function. That's fine, except the function I want to pass it to is __construct. I can't create an instance of an object with cufa(), and by instantiating an object, and then using cufa to call that instan...
Given the following classes: class Foo { struct BarBC { protected: BarBC(uint32_t aKey) : mKey(aKey) mOtherKey(0) public: const uint32_t mKey; const uint32_t mOtherKey; }; struct Bar : public BarBC { Bar(uint32_t aKey, uint32_t aOtherKey) ...
Say I have a struct that looks like this (a POD): struct Foo { int i; double d; }; What are the differences between the following two lines: Foo* f1 = new Foo; Foo* f2 = new Foo(); ...
is that correct to write a constructor like this? class A { A::A(const A& a) { .... } }; if yes, then is it correct to invoke it like this: A* other; ... A* instance = new A(*(other)); if not, what do you suggest? Thanks ...
I can't think of any reasons why one is better than the other. Compare these two implementations: public class MyClass { public MyClass(string fileName) { // some code... } } as opposed to: public class MyClass { private MyClass(){} public static MyClass Create(string fileName) { // some code....
If I have a class: class A { public A() { } } and another class B extends A { public B() { } } is there any way to get B.B() not to call A.A()? ...
We have a Java App that receives SOAP requests, and after a lot of requests we notice that the GC stops the world to unload a lot of GeneratedSerializationConstructorAccessor classes. This is a big performance impact. Does anyone know how to avoid this or at least significantly reduce the count of GeneratedSerializationConstructorAccess...
Hi, I'm learning C++. I have a simple class named GameContext: class GameContext { public: GameContext(World world); virtual ~GameContext(); }; To initialize a GameContext object, I need a World object. Should the GameContext constructur take a pointer to a World object (World*), the address to a World object (&...
I have such a set of Constructors: public BusinessObjectContext() : this(CloudStorageAccount.FromConfigurationSetting("DataConnectionString").TableEndpoint.ToString(), CloudStorageAccount.FromConfigurationSetting("DataConnectionString").Credentials) {} public BusinessObjectContext(string dataConnectionString) : ...
