An Approach to Reducing Complexity in Abstract Factory Design Pattern

It is well known that the Abstract Factory design pattern defines a new Abstract Product Factory for each family of products. Adding a new family of products affects any existing class that depends on it, and requires complex changes in the existing Abstract Factory code, as well as changes in the application or client code. Many papers discuss this issue and the issues related to increasing the number of classes. Often these papers recommend the Prototype pattern, or another solution is to add a parameter to operations that creates objects. This paper offers another approach to this issue—it employs a specially designed Factory family. Also, adding a new product is comprehensible for the existing code, and in cases when it is necessary to add a new product, all changes are implemented without any actions related to alterations or updates of existing code
