Abstract

Scalable object model design is described. In an embodiment, one or more objects corresponding to a form are instantiated in response to a request for the form from a first client device, and an events manager is instantiated through which the one or more objects register to process data manipulation events associated with the form. Data specific to the first client device is processed with the one or more objects that correspond to the form via a first processor thread. An additional request from a second client device is received and additional data specific to the second client device is processed with the one or more objects that correspond to the form via a second processor thread. The one or more objects are shared by the first client device and the second client device to process the data manipulation events associated with the form.

Claims

1. A method, comprising:

receiving a request for a form from a first client device;

instantiating a single instance of one or more objects as logic code to process data manipulation events associated with the form;

instantiating a single instance of an events manager as logic code through which the one or more objects register to process the data manipulation events associated with the form, the single instance of each of the one or more objects and the events manager being shareable across multiple processing sessions;

processing data specific to the first client device with the single instance of the one or more objects that correspond to the form via a first processor thread;

receiving an additional request for the form from a second client device;

processing additional data specific to the second client device with the single instance of the one or more objects that correspond to the form via a second processor thread such that the one or more objects are shared by the first client device and the second client device to process the data manipulation events associated with the form;

maintaining the data that is specific to the first client device with a first thread local storage; and

maintaining the additional data that is specific to the second client device with a second thread local storage.

2. A method as recited in claim 1, further comprising:

processing a second request from the first client device to process the data specific to the first client device;

obtaining the data specific to the first client device from a persisted data store;

storing the data obtained from the persisted data store in a thread local storage corresponding to the second request; and

processing the data specific to the first client device with the single instance of the one or more objects that correspond to the form.

3. A method as recited in claim 1, wherein:

the one or more objects and the events manager are instantiated when a session is established;

the single instance of each of the one or more objects and the events manager are maintained for a duration during which multiple requests from one or more additional client devices are processed; and

the one or more objects are shared by the one or more additional client devices to process the data manipulation events associated with the form.

4. A method as recited in claim 1, further comprising receiving the request from a first Web browser of the first client device as a request for an HTML form, and receiving the additional request from a second Web browser of the second client device as a request for the HTML form.

5. A method as recited in claim 1, further comprising receiving the request from a first Web browser of the first client device as a request for an HTML form represented by the one or more objects, and receiving the additional request from a second Web browser of the second client device as a request for the HTML form represented by the one or more objects.

6. A method as recited in claim 1, wherein:

the single instance of the one or more objects are instantiated as logic code associated with an HTML form displayed for viewing at the first client device and displayed for viewing at the second client device;

the request is a first user-selectable request to manipulate the data specific to the first client device and associated with the HTML form displayed at the first client device; and

the additional request is a second user-selectable request to manipulate the additional data specific to the second client device and associated with the HTML form displayed at the second client device.

7. A method as recited in claim 1, wherein each of the one or more objects and the events manager are instantiated on a side of a processor thread boundary, and wherein each of the first thread local storage and the second thread local storage are instantiated on another side of the processor thread boundary.

8. A scalable object model, comprising:

one or more objects corresponding to an interactive form, the one or more objects configured to process multiple user agent requests which are each processed on a separate processor thread;

an events manager configured to register process events associated with the interactive form;

a session established when a user agent request is received during which a single instance of each of the one or more objects and the events manager are maintained to process the multiple user agent requests such that the one or more objects are shared by the multiple user agent requests, the single instance of each of the one or more objects and the events manager being shareable across multiple processing sessions; and

a thread local storage corresponding to a particular processor thread that is associated with the user agent request, the thread local storage configured to maintain data specific to the user agent request.

9. A scalable object model as recited in claim 8, further comprising an event monitor associated with the user agent request and corresponding processor thread, the event monitor configured to notify the events manager of a process event for data that is specific to the user agent request.

10. A scalable object model as recited in claim 8, wherein:

the user agent request is received from a first Web browser of a first client device that displays the interactive form for user-interaction; and

one or more additional requests are received from Web browsers of additional client devices that each display the interactive form for user-interaction.

11. A scalable object model as recited in claim 8, wherein:

the interactive form is displayed for viewing at one or more client devices;

the user agent request is a user-initiated request to manipulate data associated with the interactive form displayed at a client device, and the data is specific to a user of the client device; and

one or more additional user agent requests are user-initiated requests to manipulate data associated with the interactive form displayed at one or more additional client devices, and the data for each additional request is specific to a user of an additional client device.

12. A scalable object model as recited in claim 8, wherein each of the one or more objects and the events manager are instantiated on a side of a processor thread boundary, and wherein the thread local storage is instantiated on another side of the processor thread boundary.

13. One or more computer readable media comprising computer executable instructions that, when executed, direct a server device to:

instantiate a single instance of one or more objects as logic code for data processing in response to a request from a first client device, the single instance of the one or more objects being shareable across multiple processing sessions;

instantiate a single instance of an events manager as logic code through which the one or more objects register data processing events;

process data specific to the first client device with the single instance of the one or more objects via a first processor thread;

process an additional request from a second client device to process additional data specific to the second client device, the additional request being processed with the single instance of the one or more objects via a second processor thread such that the one or more objects are shared by the first client device and the second client device;

maintain the data that is specific to the first client device with a first thread local storage; and

maintain the additional data that is specific to the second client device with a second thread local storage.

14. One or more computer readable media as recited in claim 13, further comprising computer executable instructions that, when executed, direct the server device to:

process a second request from the first client device to process the data that is specific to the first client device;

obtain the data that is specific to the first client device from a persisted data store;

store the data obtained from the persisted data store in a thread local storage corresponding to the second request; and

process the data specific to the first client device with the single instance of the one or more objects.

15. One or more computer readable media as recited in claim 13, further comprising computer executable instructions that, when executed, direct the server device to instantiate the single instance of the one or more objects and the single instance of the events manager when a session is established, and maintain the single instance of each of the one or more objects and the events manager for a duration during which multiple requests from one or more additional client devices are processed.

16.
