  2. Function overloading - Wikipedia

    en.wikipedia.org/wiki/Function_overloading

    The functions must have different type signatures, i.e. differ in the number or the types of their formal parameters (as in C++) or additionally in their return type (as in Ada). [9] Function overloading is usually associated with statically-typed programming languages that enforce type checking in function calls. An overloaded function is a ...

  3. Static dispatch - Wikipedia

    en.wikipedia.org/wiki/Static_dispatch

    Examples are templates in C++, and generic programming in Fortran and other languages, in conjunction with function overloading (including operator overloading). Code is said to be monomorphised , with specific data types deduced and traced through the call graph , in order to instantiate specific versions of generic functions , and select ...

  4. Ad hoc polymorphism - Wikipedia

    en.wikipedia.org/wiki/Ad_hoc_polymorphism

    The previous section notwithstanding, there are other ways in which ad hoc polymorphism can work out. Consider for example the Smalltalk language. In Smalltalk, the overloading is done at run time, as the methods ("function implementation") for each overloaded message ("overloaded function") are resolved when they are about to be executed.

  5. Multiple dispatch - Wikipedia

    en.wikipedia.org/wiki/Multiple_dispatch

    The act of creating such alternative functions for compile time selection is usually referred to as overloading a function. In programming languages that defer data type identification until run time (i.e., late binding ), selection among alternative functions must occur then, based on the dynamically determined types of function arguments.

  6. Function (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Function_(computer...

    Often the compiler selects the overload to call based on the type of the input arguments or it fails if the input arguments do not select an overload. Older and weakly-typed languages generally do not support overloading. Here is an example of overloading in C++, two functions Area that accept different types:

  7. Argument-dependent name lookup - Wikipedia

    en.wikipedia.org/wiki/Argument-dependent_name_lookup

    In the C++ Standard Library, several algorithms use unqualified calls to swap from within the std namespace. As a result, the generic std::swap function is used if nothing else is found, but if these algorithms are used with a third-party class, Foo, found in another namespace that also contains swap(Foo&, Foo&), that overload of swap will be used.

  8. Double dispatch - Wikipedia

    en.wikipedia.org/wiki/Double_dispatch

    The problem is that, while virtual functions are dispatched dynamically in C++, function overloading is done statically. The problem described above can be resolved by simulating double dispatch, for example by using a visitor pattern. Suppose the existing code is extended so that both SpaceShip and ApolloSpacecraft are given the function

  9. Overloading - Wikipedia

    en.wikipedia.org/wiki/Overloading

    The term overloading may refer to: Function overloading , a software engineering process whereby multiple functions of different types are defined with the same name Operator overloading , a software engineering process whereby operators (e.g. + or - ) are treated as polymorphic functions having different behaviors depending on the types of ...
