Computer system and method to dispatch and receive a message responsive to the occurrence of an event
View Patent ↗A computing system and method to dispatch and receive messages that are generated responsive to the occurrence of events. The server generates a message when an event such as the clicking of a mouse button occurs. This message can serve as an input for several program modules such as subroutines. A central dispatcher module is programmed with dispatching strategies to dispatch the message to a customized dispatcher module if the message is of a particular kind. The customized dispatcher module is programmed with dispatching strategies to distribute the message to the program modules. The central dispatcher module does not directly interface to the program modules. This allows for the installation and removal of the program modules without reprogramming the central dispatcher module.
1. A method for a computing system, comprising:
creating a first programmable module;
creating a customized message dispatcher module, wherein the customized message dispatcher module is not a central dispatcher module;
programming the first programmable module to receive a message only from the customized message dispatcher module if the message is generated responsive to the occurrence of an event of a particular kind; and
programming a second programmable module to receive messages directly from the first programmable module, the messages being stored in hardware on the computing system and being displayed to a user.
2. The method of claim 1 , wherein the first programmable module being created by using an application.
3. The method of claim 1 , further comprising creating and removing the second programmable module by using an application.
4. The method of claim 1 , further comprising creating and removing the second programmable module without reprogramming the customized message dispatcher module.
5. The method of claim 1 , wherein programming the second programmable module includes programming the second programmable module to receive a subset of messages received by the first programmable module from the customized message dispatcher module.
6. A storage device having stored thereon a set of instructions, which when executed by a processor, cause the processor to perform the following comprising:
creating a first programmable module;
creating a customized message dispatcher module, wherein the customized message dispatcher module is not a central dispatcher module;
programming the first programmable module to receive a message only from the customized message dispatcher module if the message is generated responsive to the occurrence of an event of a particular kind; and
programming a second programmable module to receive messages directly from the first programmable module, the messages a being stored on the storage device and being displayed to a user.
7. The storage device of claim 6 , wherein the first programmable module being created by using an application.
8. The storage device of claim 6 , further comprising creating and removing the second programmable module by using an application.
9. The storage device of claim 6 , further comprising creating and removing the second programmable module without reprogramming the customized message dispatcher module.
10. The storage device of claim 6 , wherein programming the second programmable module includes programming the second programmable module to receive a subset of messages received by the first programmable module from the customized message dispatcher module.
11. An apparatus comprising:
a message dispatcher module;
a storage device having stored therein an application;
a processor coupled to the storage device to execute the application;
the processor to create a first programmable module, to create a customized message dispatcher module, wherein the customized message dispatcher module is not a central dispatcher module, and program the first programmable module to receive a message only from the customized message dispatcher module if the message is generated responsive to the occurrence of an event of a particular kind; and
the processor to program a second programmable module to directly receive messages from the first programmable module, the messages being stored in hardware on the computing system and being displayed to a user.
12. The apparatus of claim 11 , wherein the processor creates and removes the second programmable module without reprogramming the customized message dispatcher module.
13. The apparatus of claim 11 , wherein the processor programs the second programmable module to receive a subset of messages received by the first programmable module from the customized message dispatcher module.
14. The apparatus of claim 11 , further comprising an event source to generate the event.
15. The apparatus of claim 14 , wherein the event source includes a keyboard.
16. The apparatus of claim 14 , wherein the event source includes a communications device.
17. The apparatus of claim 11 , further comprising a message generator to generate the message responsive to the occurrence of the event.
18. A computing system having a computer-readable medium storage device having stored thereon a set of instructions which when executed by a processor, cause the processor to perform the following comprising:
means for creating a first programmable module;
means for creating a customized message dispatcher module, wherein the customized message dispatcher module is not a central dispatcher module;
means for programming the first programmable module to receive a message only from a message dispatcher module if the message is generated responsive to the occurrence of an event of a particular kind; and
means for programming a second programmable module to directly receive messages from the first programmable module, said messages being stored in hardware on said computing system and being displayed to a user.
19. The computing system of claim 18 , wherein the means create and remove the second programmable module without reprogramming the customized message dispatcher module.
20. The computing system of claim 18 , wherein the means program the second programmable module to receive a subset of messages received by the first programmable module from the message dispatcher module.
21. The computing system of claim 18 , further comprising means for generating the event.
22. The computing system of claim 18 , further comprising means for generating the message responsive to the occurrence of the event.
