Object-oriented programming

object-orientedobject orientedobject-oriented programming language
A method in object-oriented programming (OOP) is a procedure associated with a message and an object.
Object-oriented programming (OOP) is a programming paradigm based on the concept of "objects", which can contain data, in the form of fields (often known as attributes or properties), and code, in the form of procedures (often known as methods).

Object (computer science)

objectobjectsdata object
A method in object-oriented programming (OOP) is a procedure associated with a message and an object.
In computer science, an object can be a variable, a data structure, a function, or a method, and as such, is a value in memory referenced by an identifier.

Property (programming)

propertiespropertyattribute or property
Data is represented as properties of the object and behaviors are represented as methods of the object.
A property, in some object-oriented programming languages, is a special sort of class member, intermediate in functionality between a field (or data member) and a method.

Method overriding

overrideoverriddenoverriding
Method overriding and overloading are two of the most significant ways that a method differs from a conventional procedure or function call. C++ also has the concept of virtual functions which are member functions that can be overridden in derived classes and allow for dynamic dispatch.
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.

Class-based programming

class-basedclass definedclass-based inheritance
In class-based programming, methods are defined in a class, and objects are instances of a given class.
In this model, objects are entities that combine state (i.e., data), behavior (i.e., procedures, or methods) and identity (unique existence among all other objects).

Message passing

message-passingmessagesmessage
A method in object-oriented programming (OOP) is a procedure associated with a message and an object.
A subroutine call or method invocation will not exit until the invoked computation has terminated.

Constructor (object-oriented programming)

Constructor (computer science)constructorscopy constructor
A constructor is a method that is called at the beginning of an object's lifetime to create and initialize the object, a process called construction (or instantiation).
A constructor resembles an instance method, but it differs from a method in that it has no explicit return type, it is not implicitly inherited and it usually has different rules for scope modifiers.

Destructor (computer programming)

destructordestructorsDestructor (computer science)
A destructor is a method that is called automatically at the end of an object's lifetime, a process called destruction.
In object-oriented programming, a destructor (sometimes abbreviated dtor ) is a method which is automatically invoked when the object is destroyed.

Encapsulation (computer programming)

These methods provide an abstraction layer that facilitates encapsulation and modularity.

Garbage collection (computer science)

garbage collectiongarbage collectorgarbage-collected
In garbage-collected languages, such as Java, C#, and Python, destructors are known as finalizers.
Methods used to manage such resources, particularly destructors, may suffice to manage memory as well, leaving no need for GC.

Finalizer

finalizedfinalizationobject finalization
In garbage-collected languages, such as Java, C#, and Python, destructors are known as finalizers.
In computer science, a finalizer or finalize method is a special method that performs finalization, generally some form of cleanup.

Type signature

method signaturesignaturetype annotation
An abstract method is one with only a signature and no implementation body.
In computer science, a type signature or type annotation defines the inputs and outputs for a function, subroutine or method.

Class (computer programming)

classclassesPartial class
In class-based programming, methods are defined in a class, and objects are instances of a given class.
In object-oriented programming, a class is an extensible program-code-template for creating objects, providing initial values for state (member variables) and implementations of behavior (member functions or methods).

Python (programming language)

PythonPython programming languagePython 2
In garbage-collected languages, such as Java, C#, and Python, destructors are known as finalizers.
Methods on objects are functions attached to the object's class; the syntax is, for normal methods and functions, syntactic sugar for.

Class implementation file

An abstract method is one with only a signature and no implementation body.
In object-oriented programming, a class implementation file is often used to contain the implementation code for the method(s) of a class.

Metaobject

metaobject protocolmeta-object protocolmetaobject protocols
Meta-model protocols allow classes to be created and deleted.
Some information that a metaobject might define includes the base object's type, interface, class, methods, attributes, parse tree, etc. Metaobjects are examples of the computer science concept of reflection, where a system has access (usually at run time) to its own internal structure.

Java (programming language)

JavaJava programming languageJava language
In garbage-collected languages, such as Java, C#, and Python, destructors are known as finalizers. The following simple Java example illustrates the difference:
The keyword in front of a method indicates a static method, which is associated only with the class and not with any specific instance of that class.

Interface (computing)

interfaceinterfacescomputer interface
Abstract methods are used to specify interfaces in some computer languages.
Applications or programs running on the operating system may need to interact via data streams, filters, and pipelines; and in object oriented programs, objects within an application may need to interact via methods.

Common Lisp Object System

CLOSCLOS MOPCommon Lisp Object System (CLOS)
But in some languages such as the Common Lisp Object System (CLOS) the meta-model allows the developer to dynamically alter the object model at run time: e.g., to create new classes, redefine the class hierarchy, modify properties, etc.
The basic building blocks of CLOS are classes and their methods, instances of those classes, and generic functions.

Abstract data type

abstract data typesabstract data structureabstract
Indeed, in many ways the object-oriented approach is simply the logical extension of previous paradigms such as abstract data types and structured programming.
The module's interface typically declares the constructors as ordinary procedures, and most of the other ADT operations as methods of that class.

Dynamic dispatch

single dispatchFat pointerruntime polymorphism
C++ also has the concept of virtual functions which are member functions that can be overridden in derived classes and allow for dynamic dispatch.
In computer science, dynamic dispatch is the process of selecting which implementation of a polymorphic operation (method or function) to call at run time.

C#Visual C#C# programming language
In garbage-collected languages, such as Java, C#, and Python, destructors are known as finalizers.
(Note: may also be called from elsewhere, like any other method, e.g. from another method of .) The static keyword makes the method accessible without an instance of.

Subroutine

A method in object-oriented programming (OOP) is a procedure associated with a message and an object.
In different programming languages, a subroutine may be called a procedure, a function, a routine, a method, or a subprogram.

Virtual function

C++ also has the concept of virtual functions which are member functions that can be overridden in derived classes and allow for dynamic dispatch.
In object-oriented programming, in languages such as C++, and Object Pascal, a virtual function or virtual method is an inheritable and overridable function or method for which dynamic dispatch is facilitated.

The main role is to allow objects to access data and invoke methods on remote objects (objects residing in non-local memory space).
