Abstract

A system for an object based notification system. The notification system is designed in a flexible manner to support change notification in an object-oriented operating system. The change notification includes a memory for storing connection information including notification routing information and connection registration information. The connection registration information is stored in a connection object of the object-oriented system and the notification system updates the connection object with registration information indicative of enablement or disablement of notification. Then, when a notification event is detected, the object-oriented operating system selectively notifies objects in the system based on the connection registration information stored in the connection object in the memory of the computer system.

Claims

1. An object-oriented notification framework system, comprising:

(a) means for connecting a plurality of objects to a notification source;

(b) memory means for storing connection information for the plurality of objects in a connection object of an object-oriented operating system;

(c) means for registering connection information, including registration information indicative of a notification status, in the connection object of the object-oriented operating system;

(d) means for selectively dispatching notification to at least one of the plurality of objects based on the registration information stored in the connection object of the object-oriented system; and

(e) means for the at least one of the plurality of objects to receive the notification and take action based on the notification.

2. A system as recited in claim 1, including processor means for notifying a plurality of objects.

3. A system as recited in claim 1, including processor means for changing a color of an object as an action based on the notification.

4. A system as recited in claim 1, including processor means for highlighting an object as an action based on the notification.

5. A system as recited in claim 1, including processor means for reverse videoing an object as an action based on the notification.

6. A system as recited in claim 1, including processor means for removing an object as an action based on the notification.

7. A system as recited in claim 1, including processor means for opening a window associated with an object as an action based on the notification.

8. A method for implementing an object-oriented notification framework system, comprising the steps of:

(a) connecting a plurality of objects to a notification source;

(b) storing connection information for the plurality of objects in a connection object of an object-oriented operating system;

(c) registering connection information, including registration information indicative of a notification status, in the connection object of the object-oriented operating system;

(d) selectively dispatching notification to at least one of the plurality of objects based on the connection registration information stored in the connection object of the object-oriented operating system; and

(e) receiving the notification by the at least one of the plurality of objects and taking action based on the notification.

9. A method as recited in claim 8, including the step of notifying a plurality of objects.

10. A method as recited in claim 8, including the step of changing a color of an object as an action based on the notification.

11. A method as recited in claim 8, including the step of highlighting an object as an action based on the notification.

12. A method as recited in claim 8, including the step of reverse videoing an object as an action based on the notification.

13. A method as recited in claim 8, including the step of removing an object as an action based on the notification.

14. A method as recited in claim 8, including the step of opening a window associated with an object as an action based on the notification.
