  3. Method overriding - Wikipedia

    en.wikipedia.org/wiki/Method_overriding

    The method Print in class Box, by invoking the parent version of method Print, is also able to output the private variables length and width of the base class. Otherwise, these variables are inaccessible to Box. The following statements will instantiate objects of type Rectangle and Box, and call their respective Print methods:

  4. Uniform access principle - Wikipedia

    en.wikipedia.org/wiki/Uniform_access_principle

    Properties, which are provided in a number of programming languages, address the problem Meyer was addressing with his UAP in a different way. Instead of providing a single uniform notation, properties provide a way to invoke a method of an object while using the same notation as is used for attribute access.

  5. typeof - Wikipedia

    en.wikipedia.org/wiki/Typeof

    In these languages, the typeof operator is the method for obtaining run-time type information. In other languages, such as C# [ 2 ] or D [ 3 ] and, to some degree, in C (as part of nonstandard extensions and proposed standard revisions ), [ 4 ] [ 5 ] the typeof operator returns the static type of the operand.

  6. Function overloading - Wikipedia

    en.wikipedia.org/wiki/Function_overloading

    The two different functions may be overloaded as Print(text_object T); Print(image_object P). If we write the overloaded print functions for all objects our program will "print", we never have to worry about the type of the object, and the correct function call again, the call is always: Print(something).

  7. Object-oriented programming - Wikipedia

    en.wikipedia.org/wiki/Object-oriented_programming

    Object-oriented programming (OOP) is a programming paradigm based on the concept of objects, [1] which can contain data and code: data in the form of fields (often known as attributes or properties), and code in the form of procedures (often known as methods).

  8. Class (computer programming) - Wikipedia

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

    The object methods include access to the object state (via an implicit or explicit parameter that references the object) whereas class methods do not. If the language supports inheritance , a class can be defined based on another class with all of its state and behavior plus additional state and behavior that further specializes the class.

  9. Forwarding (object-oriented programming) - Wikipedia

    en.wikipedia.org/wiki/Forwarding_(object...

    In object-oriented programming, forwarding means that using a member of an object (either a property or a method) results in actually using the corresponding member of a different object: the use is forwarded to another object. Forwarding is used in a number of design patterns, where some members are forwarded to another object, while others ...
