Comments on "Inversion of control"

Inversion of Control is another way of thinking about the interaction of a certain flow of actions of a piece of software are not always controlled or not necessary in control of the programmer, in which case the program acts in some cases by itself doing things without human intervention.

These automatic behaviours are often defined by another piece of software, a clear example by this can be a framework, in which the instructions and set of pre charged modules of the framework will determine the actions and the moment in which certain instructions will be called and take the role of controlling the applications activity and behaviour in an automatic way.

This, in a simple sense is a king of artificial intelligence, some pieces of software work by themselves without the need of human or the programmer’s intervention.

There is another very important concept mentioned in the article, which is Ioc, this concept is fundamental to understand how it is possible that a framework can act by itself and make decisions on its own, in order to determine when to take action an execute certain sections of our program. It makes clear, which is the difference between a framework and a library, and explains that a framework is capable of calling code from a certain source, and a library is simply the definition of any needed functions in order to make a piece of software work by extending certain functions and classes.

The Ioc method becomes quite useful when we involve the template method pattern, in the situation where a super class defines the flow of events and controls how a program will behave in a given scenario.

Some things are meant to be done in an automatic way and this king of tools become very useful, when quick and automatic decision making is crucial.
