Annotation Interface EachBean

@Documented
@Retention(RUNTIME)
@Target({METHOD,TYPE})
@Singleton
public @interface EachBean

This annotation allows driving the production of Bean definitions from presence of other bean definitions. Typically used in conjunction with EachProperty

For example:

 @EachProperty("foo.bar")
  public class ExampleConfiguration {
  }

In the above example a new ExampleConfiguration bean will be created for each item under the foo.bar key in application configuration

One can then drive the configuration of other beans with the same annotation:

 @EachBean(ExampleConfiguration)
 @Singleton
  public class ExampleBean {
     ExampleBean(ExampleConfiguration config) {
         ...
     }
  }

EachBean requires that the parent bean has a Named qualifier, since the qualifier is inherited by each bean created by EachBean.
