Inversion of Control Containers and the Dependency Injection pattern

Posted on by

Some time ago I have posted an article called Aragon Container, in which I tried to explain the idea behind the bigest building block of the Aragon Framework.

Today I ran into the article I have found long time ago, which cleared the fogg behind the Inversion of Control and Dependency Injection patterns. This article was written somewhere back in 2004 by the OOP guru Martin Fowler and I could not help it to share this with You, it might help understand what I wanted to explain in my article.

Since I know that I am no good writer, I have to find some ways to make you understand what I am talking about. The only ways I can see, are some high quality articles related to the discussed topics written by those having more experience in teaching than me…

So here is the article I have talking about:

  2. http://www.devx.com/Java/Article/27583
  3. http://en.wikipedia.org/wiki/Dependency_injection

Until next time

I wish you happy coding.

Her husband had to totally reinvent himself and was yearning to fulfill a dream with a new vocation. She was happy for him and supported him fully, but still the money was not coming in.
