public class ContextEventRecorder
extends ContextSubscriber

This class records all events at the context-bus by registering itself with a generic pattern (subject need to be a resource, what is true anyway). Since URI's are heavily need to be used for creation of Situations and Queries it can be helpful to show a user a selection of all URI's that up to now has passed the system. All results will be saved and therefore are available again after restarting the system.
