Three Wise Men

Sketchy musical factory

Today we will take a look at the abstract factory design pattern. This design pattern continues the series of creational patterns.

In previous article we have talked about factory pattern. We have learned that factory pattern deals with creation of other objects. Now we will extend that knowledge with the abstract factory pattern which provides a way to group together or rather encapsulate a group of individual factories that create objects with common theme.

Normally we would code a client software to create a concrete implementation of the abstract factory and then use generic interfaces to create concrete objects that are tuned to specific theme but, the client does not know about which concrete object will it get from each of the internal factories since it uses generic interfaces of the factory product in question. Details of the implementation of concrete objects are hidden by the internal factories.

Next creational pattern that we will have a closer look at – is Factory pattern. There are at least two different Factory patterns, Factory method and Abstract Factory. In this installment we will be looking at the Factory method pattern.

Now from my perspective there are a lot of programmers that finish school, get a degree, get a good job and then are presented with a problem. For example program designers design applications that include one of most simple design patterns.

Now I am not the best programmer in the world and also not the worst. Maybe I was lucky to be born in the era in which pattern design sprouted and started to grow. Also I know that most of you dear readers don’t need to reread this simple stuff, but if you are unsure of something … go ahead and take a peek. We will not tell ;)

This should be a first of design pattern series. So come back and check out the one of which you are unsure of. READ MORE
