Dependency injection – Wikipedia entry

Dependency injection (DI) in object-oriented computer programming is a design pattern with a core principle of separating behavior from dependency resolution. In other words: a technique for decoupling highly dependent software components. Developers of software strive to reduce dependencies between components in software for various reasons. This leads to a new problem, though: How can… Continue reading Dependency injection – Wikipedia entry

Inversion of Control Containers and the Dependency Injection pattern – Martin Fowler’s seminal article

Separating Configuration from Use The important issue in all of this is to ensure that the configuration of services is separated from their use. Indeed this is a fundamental design principle that sits with the separation of interfaces from implementation. It’s something we see within an object-oriented program when conditional logic decides which class to… Continue reading Inversion of Control Containers and the Dependency Injection pattern – Martin Fowler’s seminal article
