+<P>The architecture feature allows obtaining an architectural / component view of your systems. It exposes a snapshot of the present instances & factories, the state of these instances ...<BR>

+
+<P>The architecture feature does "reflection" on the iPOJO containers. It gathers information about the component (state, class name ...), requirement (state, multiple, optional ...), provided services (state, properties) ... Each handler can participate to the architecture. This information allows you to know why an instance does not start, or why the component does not publish / provide a service.</P>
