Is there a DI framework comparable to Google Guice? And what does Google use?
Spring.NET is one of the popular open source frameworks for Dependency Injection. Spring.NET supports . NET 4.0, . NET Client Profile 3.5 and 4.0, Silverlight 4.0 and 5.0, and Windows Phone 7.0 and 7.1.
Using dependency injection, we can pass an instance of class C to class B, and pass an instance of B to class A, instead of having these classes to construct the instances of B and C. In the example, below, class Runner has a dependency on the class Logger.
The IServiceProvider is responsible for resolving instances of types at runtime, as required by the application. These instances can be injected into other services resolved from the same dependency injection container. The ServiceProvider ensures that resolved services live for the expected lifetime.
There is nothing as mature or standard as Guice in the C++ world. However, some people have put together simplistic implementations on their own. Here's a couple.
You're unlikely to be satisfied by any of these.
If you really wanted to put in the effort to rally the world around a DI framework for C++, probably the way to go about it would be to make a proposal to the Boost guys.
