Factory (object-oriented programming)

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^[1] from some method call, which is assumed to be "new".^[a] More broadly, a subroutine that returns a "new" object may be referred to as a "factory", as in factory method or factory function. The factory pattern is the basis for a number of related software design patterns.
