libguice-java - 4.2.3-2 main

Guice provides support for dependency injection using annotations to
configure Java objects. Dependency injection is a design pattern whose
core principle is to separate behavior from dependency resolution.
.
Guice allows implementation classes to be programmatically bound to
an interface, then injected into constructors, methods or fields
using an @Inject annotation. When more than one implementation of
the same interface is needed, the user can create custom annotations
that identify an implementation, then use that annotation when
injecting it.
