Examples of MutablePicoContainer

org.picocontainer.MutablePicoContainer
This is the core interface used for registration of components with a container. It is possible to register {@link #registerComponentImplementation(Object,Class) an implementation class}, {@link #registerComponentInstance(Object) aninstance} or {@link #registerComponent(ComponentAdapter) a ComponentAdapter}. @author Paul Hammant @author Aslak Hellesøy @author Jon Tirsén @version $Revision: 1800 $ @see See package description for basic overview how to use PicoContainer. @since 1.0
