-/**
- * This class allows to inject into objects through a base class,
- * so we don't have to repeat injection code everywhere.
- *
- * The performance drawback is about 0.013 ms per injection on a very slow device,
- * which is negligible in most cases.
- *
- * Example:
- * <pre>{@code
- * Component {
- *     void inject(B b);
- * }
- *
- * class A {
- *     void onCreate() {
- *         componentReflectionInjector.inject(this);
- *     }
- * }
- *
- * class B extends A {
- *     @Inject MyDependency dependency;
- * }
- *
- * new B().onCreate() // dependency will be injected at this point
- *
- * class C extends B {
- *
- * }
- *
- * new C().onCreate() // dependency will be injected at this point as well
