Patent Images
1. A system for visualizing objects within a distributed object system, the system comprising:
- a plurality of objects, each object having an associated filter arranged to intercept messages sent or received by its corresponding object and to forward information representative of said messages to an event collector in addition to forwarding on said messages to their respective destinations; and
a visualizer application operatively coupled to the event collector and arranged to receive the information from said event collector and having a graphical front-end for displaying to a user a graphical representation of the distributed object system, the visualizer application being user configurable to display a selected category of objects within the system.

Abstract
A Distributed Object System includes an Event Collection Mechanism (14) which receives information on the creation, deletion and actuation of objects within the system. The Event Collection Mechanism passes on the collected events to an Event Dispatch Mechanism (16) with which user applications may register. The Event Dispatch Mechanism forwards details of events to the User Applications, according to the criteria selected by the user. A method is provided for linking all reported events back to the object which was ultimately responsible for their creation.

20. A method of characterising a distributed object system having a plurality of objects, the method comprising:
-
providing each object with an associated filter which is arranged to intercept messages sent or received by its corresponding object and to forward information representative of said messages to an event collector in addition to forwarding on said messages to their respective destinations, the distributed object system being characterised according to the messages received by the event collector; and
providing the information to a visualizer application, operatively coupled to the event collector to receive the information from the event collector, having a graphical front-end for displaying to a user a graphical representation of the distributed object system, the visualizer application being user configurable to display a selected category of objects within the system.
