actual version 2.0


definition IOC & DI source: http://wikipedia.com


Dependency injection is a software design pattern that allows a choice of component to be made at run-time rather than compile time. This can be used, for example, as a simple way to load plugins dynamically or to choose mock objects in test environments vs. real objects in production environments.

In software engineering, Inversion of Control (IoC) is an object-oriented programming practice whereby the object coupling is bound at run time by an "assembler" object and is typically not knowable at compile time using static analysis.
