Class AnnotatedFieldInjector

java.lang.Object
  extended by org.picocontainer.adapters.AbstractAdapter<T>
      extended by org.picocontainer.injectors.AbstractInjector<T>
          extended by org.picocontainer.injectors.IterativeInjector
              extended by org.picocontainer.injectors.AnnotatedFieldInjector
All Implemented Interfaces:
Serializable, ComponentAdapter, ComponentMonitorStrategy, Injector

public class AnnotatedFieldInjector
extends IterativeInjector

Injection happens after instantiation, and through fields marked as injection points via an Annotation. The default annotation of org.picocontainer.annotations.@Inject can be overridden.
