Examples of org.picocontainer.PicoContainer

org.picocontainer.PicoContainer
This is the core interface for PicoContainer. It is used to retrieve component instances from the container; it only has accessor methods (in addition to the {@link #verify()} method). In order to register components in aPicoContainer, use a {@link MutablePicoContainer}, such as {@link org.picocontainer.defaults.DefaultPicoContainer}. @author Paul Hammant @author Aslak Hellesøy @author Jon Tirsén @version $Revision: 1820 $ @see See package description for basic overview how to use PicoContainer. @since 1.0
