  2. Function overloading - Wikipedia

    en.wikipedia.org/wiki/Function_overloading

    Function overloading is usually associated with statically-typed programming languages that enforce type checking in function calls. An overloaded function is a set of different functions that are callable with the same name. For any particular call, the compiler determines which overloaded function to use and resolves this at compile time ...

  3. 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

  4. Ad hoc polymorphism - Wikipedia

    en.wikipedia.org/wiki/Ad_hoc_polymorphism

    Ad hoc polymorphism is a dispatch mechanism: control moving through one named function is dispatched to various other functions without having to specify the exact function being called. Overloading allows multiple functions taking different types to be defined with the same name; the compiler or interpreter automatically ensures that the right ...

  5. Method (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Method_(computer_programming)

    Method overloading, on the other hand, refers to differentiating the code used to handle a message based on the parameters of the method. If one views the receiving object as the first parameter in any method then overriding is just a special case of overloading where the selection is based only on the first argument.

  6. Method overriding - Wikipedia

    en.wikipedia.org/wiki/Method_overriding

    Illustration. Method overriding, in object-oriented programming, is a language feature that allows a subclass or child class to provide a specific implementation of a method that is already provided by one of its superclasses or parent classes.

  7. Virtual function - Wikipedia

    en.wikipedia.org/wiki/Virtual_function

    For this reason, calling virtual functions in constructors is generally discouraged. In C++, the "base" function is called. Specifically, the most derived function that is not more derived than the current constructor or destructor's class is called. [7]: §15.7.3 [8] [9] If that function is a pure virtual function, then undefined behavior occurs.

  8. 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 ...

  9. JavaScript syntax - Wikipedia

    en.wikipedia.org/wiki/JavaScript_syntax

    Function declarations, which declare a variable and assign a function to it, are similar to variable statements, but in addition to hoisting the declaration, they also hoist the assignment – as if the entire statement appeared at the top of the containing function – and thus forward reference is also possible: the location of a function ...
