Injection API

Control how your classes get instantiated by Lighter. The primary class applications will interact with is the InjectionObjectFactory. This functional interface is designed to provide a implementation agnostic API for dependency injection containers. The interface is very simple as it is only used when Lighter needs to construct a class for the application.

The interface is designed to match the Guice Injector#newInstance method.

The other class used for dependency construction is the ReverseInjector. Implementations of ReverseInjector provide an instance of InjectionObjectFactory. Lighter will automatically generate an implementation of ReverseInjector that has a setter for every dependency Lighter will need to construct. The auto generated implementation conforms to Java Beans and javax.Inject standards for dependency Injection. This implementation can be used as a configuration bean with dependency injection frameworks that do not have an Injector class (like Dagger 2).
