Aug 1, 2012 · Found this answer to make it work under MSVC 2010. If anybody's confused as to how to use the EXPAND mentioned in @Étienne's link, you basically invoke it on GET_MACRO like so #define FOO(...) EXPAND(GET_MACRO(__VA_ARGS__, FOO3, FOO2, FOO1)(__VA_ARGS__)) and it should expand to the right number of arguments in msvc.
a += a; This gets translated into. a.operator+= (a); And so the code will operate with both the parameter and the receiver being the same object. This usually doesn't come up for compound assignment operators (usually only operator= needs to worry about this), but in some cases you can get burned if you're not careful.
In general I think the base class should define a operator== overload (internally or via friend class doesn't matter) which check typeid equality and calls an abstract virtual "equals" function which the derived class will define. In that function the derived class could even use static_cast because the typeid is already been checked to be the ...
Dec 12, 2010 · If you overload operator new, you should always also overload the matching operator delete, even if you never intend to call it. The reason is that, if a constructor throws during the evaluation of a new expression, the run-time system will return the memory to the operator delete matching the operator new that was called to allocate the memory to create the object in.
Jan 1, 2016 · 109. You can use "roll-your-own" solution for function overloading. This one is copied from Guido van Rossum's article about multimethods (because there is little difference between multimethods and overloading in Python): registry = {} class MultiMethod(object): def __init__(self, name): self.name = name.
Mar 23, 2009 · 1. Overloading is a part of static polymorphism and is used to implement different method with same name but different signatures. Overriding is used to complete the incomplete method. In my opinion there is no comparison between these two concepts, the only thing is similar is that both come with the same vocabulary that is over.
Nov 14, 2008 · Overloading, or "method overloading" is the name of the concept of having more than one methods with the same name but with different parameters. For e.g. System.DateTime class in c# have more than one ToString method. The standard ToString uses the default culture of the system to convert the datetime to string:
35. The [] operator is called an indexer. You can provide indexers that take an integer, a string, or any other type you want to use as a key. The syntax is straightforward, following the same principles as property accessors. For example, in your case where an int is the key or index: public int this[int index] {. get => GetValue(index);
Therefore, in a strict sense, one could argue that TS function overloading doesn't exists. However, there are things you can do within your TS code that can perfectly mimick function overloading. Here is an example: function add(a: number, b: number, c: number): number; function add(a: number, b: number): any; function add(a: string, b: string ...
The way this is useful for function overloading is that it can be inserted by the C preprocessor and choose a result expression based on the type of the arguments passed to the controlling macro. So (example from the C standard): #define cbrt(X) _Generic((X), \. long double: cbrtl, \. default: cbrt, \.
