Contrary to what others are saying, overloading by return type is possible and is done by some modern languages. The usual objection is that in code like int func(); string func(); int main() { func(); } you can’t tell which func() is being called. This can be resolved in a few ways: Have a predictable … Read more
Yes! In the time since this question was asked, standard C (no extensions) has effectively gained support for function overloading (not operators), thanks to the addition of the _Generic keyword in C11. (supported in GCC since version 4.9) (Overloading isn’t truly “built-in” in the fashion shown in the question, but it’s dead easy to implement … Read more
What you are asking for is called multiple dispatch. See Julia language examples which demonstrates different types of dispatches. However, before looking at that, we’ll first tackle why overloading is not really what you want in Python. Why Not Overloading? First, one needs to understand the concept of overloading and why it’s not applicable to … Read more
You can use the attribute if you want your code to do overloading. [ActionName(“MyOverloadedName”)] But, you’ll have to use a different action name for the same http method (as others have said). So it’s just semantics at that point. Would you rather have the name in your code or your attribute? Phil has an article … Read more
When you overload in TypeScript, you only have one implementation with multiple signatures. class Foo { myMethod(a: string); myMethod(a: number); myMethod(a: number, b: string); myMethod(a: any, b?: string) { alert(a.toString()); } } Only the three overloads are recognized by TypeScript as possible signatures for a method call, not the actual implementation. In your case, I … Read more
The clearest way to express polymorphism is via an abstract base class (or interface) public abstract class Human{ … public abstract void goPee(); } This class is abstract because the goPee() method is not definable for Humans. It is only definable for the subclasses Male and Female. Also, Human is an abstract concept — You … Read more
TypeScript allows you to declare overloads but you can only have one implementation and that implementation must have a signature that is compatible with all overloads. In your example, this can easily be done with an optional parameter as in, interface IBox { x : number; y : number; height : number; width : number; … Read more
Go does not have optional parameters nor does it support method overloading: Method dispatch is simplified if it doesn’t need to do type matching as well. Experience with other languages told us that having a variety of methods with the same name but different signatures was occasionally useful but that it could also be confusing … Read more
The best way to do function overloading with parameters is not to check the argument length or the types; checking the types will just make your code slow and you have the fun of Arrays, nulls, Objects, etc. What most developers do is tack on an object as the last argument to their methods. This … Read more
No, the structure you found is how Java handles it (that is, with overloading instead of default parameters). For constructors, See Effective Java: Programming Language Guide’s Item 1 tip (Consider static factory methods instead of constructors) if the overloading is getting complicated. For other methods, renaming some cases or using a parameter object can help. … Read more
