  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. Operator overloading - Wikipedia

    en.wikipedia.org/wiki/Operator_overloading

    Scala treats all operators as methods and thus allows operator overloading by proxy. In Raku, the definition of all operators is delegated to lexical functions, and so, using function definitions, operators can be overloaded or new operators added. For example, the function defined in the Rakudo source for incrementing a Date object with "+" is:

  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

    Non-virtual or static methods cannot be overridden. The overridden base method must be virtual, abstract, or override. In addition to the modifiers that are used for method overriding, C# allows the hiding of an inherited property or method. This is done using the same signature of a property or method but adding the modifier new in front of it ...

  7. Double dispatch - Wikipedia

    en.wikipedia.org/wiki/Double_dispatch

    In C#, when calling an instance method accepting an argument, multiple dispatch can be achieved without employing the visitor pattern. This is done by using traditional polymorphism while also casting the argument to dynamic. [3] The run-time binder will choose the appropriate method overload at run-time.

  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. Java syntax - Wikipedia

    en.wikipedia.org/wiki/Java_syntax

    Unlike in C++, methods in Java are not allowed to have default argument values and methods are usually overloaded instead. class Foo { int bar ( int a , int b ) { return ( a * 2 ) + b ; } /* Overloaded method with the same name but different set of arguments */ int bar ( int a ) { return a * 2 ; } }
