Annotation Interface Inject

@Retention(CLASS)
@Target({METHOD,FIELD})
public @interface Inject

Used to annotate a method or field as an injection point.

The method or field must not be private, usually it's best to have it package-private.

Usage example:

      public class MyClass
      {
         private TransactionManager tm;
         private BuddyManager bm;
         private Notifier n;

         &Inject
         public void setTransactionManager(TransactionManager tm)
         {
            this.tm = tm;
         }

         &Inject
         public void injectMoreStuff(BuddyManager bm, Notifier n)
         {
            this.bm = bm;
            this.n = n;
         }
      }

and an instance of this class can be constructed and wired using

      MyClass myClass = componentRegistry.getComponent(MyClass.class);

Methods annotated with this Inject annotation should *only* set class fields. They should do nothing else. If you need to do some work to prepare the component for use, do it in a Start method since this is only called once when a component starts.
