Inversion of control (IoC), Dependency injection (DI)

Dependency injection 2

Dependency injection (DI)


“Dependency injection (DI) in object-oriented computer programming is a technique that indicates to a part of a program which other parts it can use, i.e. to supply an external dependency, or reference, to a software component. More simply, dependency injection is the passing or setting of dependencies into a software component. In technical terms, it is a design pattern that separates behavior from dependency resolution, thus decoupling highly dependent components. Instead of components having to request dependencies, they are given, or injected, into the component.”

Inversion of Control (IoC) 2

Inversion of control (IoC)

“In software engineering, Inversion of control (IoC) is an abstract principle describing an aspect of some software architecture designs in which the flow of control of a system is inverted in comparison to procedural programming.
In traditional programming the flow of the business logic is controlled by a central piece of code, which calls reusable subroutines that perform specific functions. Using Inversion of Control this “central control” design principle is abandoned. The caller’s code deals with the program’s execution order, but the business knowledge is encapsulated by the called subroutines.
In practice, Inversion of Control is a style of software construction where reusable generic code controls the execution of problem-specific code. It carries the strong connotation that the reusable code and the problem-specific code are developed independently, which often results in a single integrated application.”
