Factory object oriented programming
WebMar 25, 2013 · A C++ object factory. Source code; The Problem. In object oriented programming, it is very common to have a scenario where a large number of classes share the same base class and the particular implementation needs to be created at runtime based on some specific parameters, for example a class name held in a string. ... WebNov 27, 2015 · Yes, you would have Factory of Factories. The key point is that this either class or method should be in topmost library/application. Only smallest possible part of the application should know about this FoF. It could very well be a simple method in launcher of the application that is executed before the main loop of the application executes.

Web1. Object Oriented Programming is a programming methodology or concept of programming that organizes code into objects and relationships of objects. Design Patterns would suggest proven-successful methods of constructing types/objects to solve a certain scenario in a program. This is a limited definition. In object-oriented programming, a factory is an object for creating other objects; formally, it is a function or method that returns objects of a varying prototype or class from some method call, which is assumed to be "new". More broadly, a subroutine that returns a "new" object may be referred to as a … See more In class-based programming, a factory is an abstraction of a constructor of a class, while in prototype-based programming a factory is an abstraction of a prototype object. A constructor is concrete in that it creates objects as … See more Terminology differs as to whether the concept of a factory is itself a design pattern – in Design Patterns there is no "factory pattern", but instead two patterns (factory method pattern and abstract factory pattern) that use factories.
