Features

---

Currently supports minimal features as I've just started working on the project.

@Inject annotation to inject a field (Constructor injection is not yet supported :( )

@Prototype annotation to define concrete classes you want injected as prototype (New instance each with object instantion)

@Singleton annotation to define concrete classes as singleton (One instance for all objects)

Example code:

  public static void main(String[] args) {
        DependencyProvider dependencyProvider=new DependencyProvider();
        Injector injector=new Injector(dependencyProvider);
        injector.getMappingService().bindClassToClass(TestInterface.class,TestConcrete.class);
        TestObject obj = injector.createInstance(TestObject.class);
        }

Yay! TestObject was injected with a TestConcrete object! Wow!
