Class NamedFieldInjector<T>

java.lang.Object
  org.picocontainer.adapters.AbstractAdapter<T>
      org.picocontainer.injectors.AbstractInjector<T>
          org.picocontainer.injectors.IterativeInjector<T>
              org.picocontainer.injectors.AbstractFieldInjector<T>
                  org.picocontainer.injectors.NamedFieldInjector<T>

All Implemented Interfaces:

Serializable, ComponentAdapter<T>, ComponentMonitorStrategy, Injector<T>

public class NamedFieldInjector<T>
extends AbstractFieldInjector<T>

Injection happens after instantiation, and fields are marked as injection points via a named field.
