public final class ComponentViewer

implements org.apache.avalon.framework.activity.Startable, java.awt.event.ActionListener, java.lang.Runnable

Simple Fortress container containing a Swing based viewer for performing lookups on registered components.

The intention of the viewer is to allow you to perform a lookup of a component manually, (currently) so you can check the see the effect of lazy vs startup initialization.

REVISIT: add a text component which tracks the log file to make it easier to see a component being initialized upon first lookup.
