	Object-oriented programming - Wikipedia, the free encyclopedia
		Object-oriented programming developed as the dominant programming methodology during the mid-1980s, largely due to the influence of C++, an extension of the C programming language.
		In computer science, object-oriented programming, OOP for short, is a computer programming paradigm.
		Inheritance- Organizes and facilitates polymorphism and encapsulation by permitting objects to be defined and created that are specialized types of already-existing objects - these can share (and extend) their behavior without having to reimplement that behavior.
	en.wikipedia.org /wiki/Object-oriented_programming

	Inheritance (computer science) - Wikipedia, the free encyclopedia
		In object-oriented programming, inheritance is a way to form new classes (instances of which will be objects) using pre-defined objects or classes where new ones take over old ones' implementations and characteristics.
		Many object-oriented programming languages permit a class or object to replace the implementation of an aspect—typically a behavior—that it has inherited.
		Inheritance is often better used with a generalization mindset, such that common aspects of instantiable classes are factored to superclasses; say having a common superclass 'LegalEntity' for both Person and Company classes for all the common aspects of both.

	Java programming language article - Java programming language object-oriented programming language James Gosling Microsystems - What-Means.com
		Objects are created and placed at an address on the heap.
		Java's heavy use of heap-allocated objects causes programs to consume more memory than similar programs written in lower-level languages, where data storage can be optimized at a fine granularity.
		The program or other objects can reference an object by holding a reference to its address on the heap.

	Talk:Inheritance (object-oriented programming) - Wikipedia, the free encyclopedia
		The article Inheritance (computer science) can discuss inheritance outside of the OOP context then; inheritance in an OOP context is of sufficient depth and complexity to deserve its own article, since that is where it is predominantly (or always, depending on your perspective) used; thus: Inheritance (object-oriented programming).
		Object based languaged do NOT follow the object oriented paradigm, that is why they are called object based and NOT object-oriented and that is why object based languages do not have inheritance.
		Inheritance in genetic algorithms is discussed fully in genetic algorithm there is no need to have an article sepifically about inheritance in genetic algorithms because inheritance in that context is 99% of the subject.

	How Object-Oriented Programming Started
		Simula 67 introduced most of the key concepts of object-oriented programming: both objects and classes, subclasses (usually referred to as inheritance) and virtual procedures, combined with safe referencing and mechanisms for bringing into a program collections of program structures described under a common class heading (prefixed blocks).
		Instead object-oriented programming is today (in the late 1990s) becoming the dominant style for implementing complex programs with large numbers of interacting components.
		When the inheritance mechanism was invented in 1967, Simula 67 was developed as a general programming language that also could be specialised for many domains, including system simulation.

	object-oriented programming - a Whatis.com definition - see also: OOP, object-oriented
		Object-oriented programming takes the view that what we really care about are the objects we want to manipulate rather than the logic required to manipulate them.
		Object-oriented programming (OOP) is a programming language model organized around "objects" rather than "actions" and data rather than logic.
		The definition of a class is reuseable not only by the program for which it is initially created but also by other object-oriented programs (and, for this reason, can be more easily distributed for use in networks).

	Object-Oriented Programming Concepts
		A class is a blueprint or prototype that defines the variables and the methods common to all objects of a certain kind.
		You need to understand what an object is, what a class is, how objects and classes are related, and how objects communicate by using messages.
		Software objects are often used to model real-world objects you find in everyday life.

	DBMS - June 1996 - Object-Oriented Analysis and Design
		You must be able to recognize quickly if the object methodology isn't working for your particular project, and you must find another approach that does work, whether it is object oriented or not.
		Inheritance (also referred to as generalization/specialization) is usually identified by the phrase "is a kind of." For example, Student and Faculty are both a kind of Person and are therefore inherited from the Person class.
		Object modeling and many other OO concepts in Objectory and OOSE are similar to OO concepts in other methodologies.

	Object Oriented Programming in C
		The distinction between class and object operations is not particularly important unless you are using an object-oriented language, suffice to say that operations that concern objects in general (e.g.
		Many of an object's functions are very simple, often only one or two commands, but because they are functions they incur the overhead of a function call and return every time they are used.
		In an object based world the only way for anything to happen is by objects communicating with each other and acting on the results.

		We'll teach you how to establish prototyping, how to detect whether one object is a prototype of another object, and how JavaScript's model is different from Java's object-oriented programming.
		Even though there are no classes and instances, there are objects, prototypes, and implicit inheritance.
		Prototyping is the key to understanding the inheritance concept.

	What is Object-Oriented Software? An Introduction
		However, to take full advantage of object-oriented programming, one must program (and think!) in C++, not C. This can often be a major problem for experienced C programmers.
		Object a, receive this message and perform the action requested, which is to add the value of the argument to yourself.
		The object which a message is sent to is called the receiver of the message.

	Object Oriented Fortran 90 Programming
		We have written a variety of object-oriented plasma particle-in-cell programs on sequential workstations and high performance distributed memory computers in Fortran 90 and C++.
		While the array-syntax notation has received the most attention, we have found that many modern software development techniques can be supported by this language, including object-oriented concepts.
		Other concepts, such as inheritance and dynamic dispatching, are not supported directly, but can be emulated.

		This is surprising, considering that encapsulation is one of the most fundamental and important concepts behind object-oriented programming and that it is essential for writing programs that are maintainable and reliable, and that remain robust as they evolve."
		With Traits, classes are still organized in a single inheritance hierarchy, but they can make use of Traits to specify the incremental difference in behavior with respect to their superclasses.
		As there are somethings that can be done with "manifest typed" programs that can't be done with dynamic programs, the reverse is also especially true: untyped, non-typed, or dynamic programs have special capabilities that typed systems don't have.

	JOT: Journal of Object Technology -Understanding Symmetry in Object-Oriented Languages, Zhao, Coplien
		In object-oriented programming, the role of inheritance in classification is not as clear as that of classes.
		For example, Wegner [27] presents a classification paradigm for object-oriented programming.
		Cardelli [5] states that classification is what makes object-oriented programming different from other programming paradigms.

	Object Oriented Programming
		In a loose sense, Object Oriented Programming is based on the idea that one deals with a community of communicating objects.
		Inheritance is single, meaning MOO objects can only inherit from a single Generic Object.
		This is in contrast to most OO Languages, where inheritance is disciplined by a subclass relation between abstract ``classes'' that do not function as actual objects - called ``instances''.

	Glossary
		A method of programming in which programs are organized as cooperative collections of objects, each of which represents an instance of some type, and whose types are all members of a hierarchy of types united via other than inheritance relationships.
		A method of implementation in which programs are organized as cooperative collections of objects, each of which represents an instance of some class, and whose classes are all members of a hierarchy of classes united via inheritance relationships.
		The purpose or capacity wherein one class or object participates in a relationship with another; the role of an object denotes the selection of a set of behaviors that are well-defined at a single point in time; a role is the face an object presents to the world at a given moment.

	OOP Criticism
		OOP is best used for situations where an OOP program or language should knowingly and exclusively have nearly complete control over the birth, processing, and death of data items (objects).
		The inheritance and aggregation model of OOP tends to assume the world can be cleanly modeled as hierarchical classification and/or nested structures, or at least into mutually-exclusive divisions (a flat tree), when in fact this is often not the case.
		OOP is more of a program organizational philosophy rather than a set of new external solutions or operations.

		Many object-oriented programming languages permit a class or object to replace the implementation of an aspect—typically a behavior—that it has inherited.
		The difference between roles and classes is especially difficult to understand if referential transparency is assumed, because roles are types of references and classes are types of the referred-to objects.

	Survey of Object Oriented Programming Languages
		Object oriented features of C++ include: Virtual (abstract) functions - resulting in virtual classes, public/private/protected access control over individual member functions and attributes, friend classes (for allowing explicitly named classes to access private state), nested classes, multiple inheritance (for sub-typing and code sharing) with method redefinition, and templated (generic) classes and functions.
		With all the various ``Object Oriented Programming Languages'' and ``Object Oriented Processes'' and ``Object Oriented Basket Weaving'' in the world today, it seems that establishing a clear definition of what it means to be object oriented, is impossible.
		``...object oriented programming will be in the 1980's what structured programming was in the 1970's.
