  2. Method overriding - Wikipedia

    en.wikipedia.org/wiki/Method_overriding

    In Ruby when a subclass contains a method that overrides a method of the superclass, you can also call the superclass method by calling super in that overridden method. You can use alias if you would like to keep the overridden method available outside of the overriding method as shown with 'super_message' below. Example:

  3. Dynamic dispatch - Wikipedia

    en.wikipedia.org/wiki/Dynamic_dispatch

    Smalltalk uses a type-based message dispatcher. Each instance has a single type whose definition contains the methods. When an instance receives a message, the dispatcher looks up the corresponding method in the message-to-method map for the type and then invokes the method. Because a type can have a chain of base types, this look-up can be ...

  4. C Sharp syntax - Wikipedia

    en.wikipedia.org/wiki/C_Sharp_syntax

    A constructor is a special method that is called automatically when an object is created. Its purpose is to initialize the members of the object. Constructors have the same name as the class and do not return anything explicitly. Implicitly, they will return the newly created object when called via the new operator. They may take parameters ...

  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. C Sharp (programming language) - Wikipedia

    en.wikipedia.org/wiki/C_Sharp_(programming_language)

    Microsoft first used the name C# in 1988 for a variant of the C language designed for incremental compilation. [37] That project was not completed, and the name was later reused. C-sharp musical note. The name "C sharp" was inspired by the musical notation whereby a sharp symbol indicates that the written note should be made a semitone higher ...

  7. Method chaining - Wikipedia

    en.wikipedia.org/wiki/Method_chaining

    Method chaining is a common syntax for invoking multiple method calls in object-oriented programming languages. Each method returns an object, allowing the calls to be chained together in a single statement without requiring variables to store the intermediate results.

  8. Factory method pattern - Wikipedia

    en.wikipedia.org/wiki/Factory_method_pattern

    In object-oriented programming, the factory method pattern is a design pattern that uses factory methods to deal with the problem of creating objects without having to specify their exact classes. Rather than by calling a constructor, this is accomplished by invoking a factory method

  9. Call super - Wikipedia

    en.wikipedia.org/wiki/Call_super

    Call super is a code smell or anti-pattern of some object-oriented programming languages. Call super is a design pattern in which a particular class stipulates that in a derived subclass, the user is required to override a method and call back the overridden function itself at a particular point. The overridden method may be intentionally ...
