【0026】

Features, advantages, and the like of the present invention are described in, or clearly understood from, the following detailed description of various aspects of systems and methods according to the present invention.

【0027】

BEST MODE FOR CARRYING OUT THE INVENTION

Frameworks for developing web applications are provided according to various embodiments of the present invention. This framework provides routines or virtual machines for web objects. According to various embodiments of the present invention, a web object is a template-driven mechanism that constructs a web page through the use of objects, state machines, events and actions within states. .. The web object defines an explicit relationship between state machines, events and actions in a state that operate in parallel. The web object provides a persistent state machine view of the components of the web application.

【0028】

Events can send messages and / or information to web objects. Web objects can receive events from external sources, such as web browsers or other web objects. In various embodiments, each web browser can contain data and / or be addressed.

【0029】

The state of a web object provides a history of past events and allows the web object to modify its response to new events based on the history of past events for that web object. Thus, in various embodiments, the web object can receive and send events that can cause the web object to change state and perform actions associated with that state.

【0030】

In various embodiments, the actions defined within a web object specify how the web object reacts to the events received by that web object. For example, an event may cause a web object to modify data contained within that web object and / or other web objects. Alternatively, or in addition, the event may cause the web object to change state and / or generate an event. The generated event may be sent to an external entity such as a web browser, or another web object. For example, a web object's action in a state collects read and written data from one or more external devices, displays that data in a web browser, writes to other web objects, and / or external devices. May be written in.

【0031】

In various embodiments of the system and method according to the present invention, the web object system comprises a mechanism for the persistence of the web object. This persistence mechanism allows a web object to maintain its state for a long period of time regardless of any demands the web object receives. For example, the state of a web object may be stored in a persistent storage mechanism such as the underlying database.

【0032】

According to various embodiments of the present invention, the web object system also includes an event dispatcher as part of its run-time software. The event dispatcher queues events and sends each event in a predictable way to the destination specified by that particular event. For example, when an event is generated by an external source, such as an HTTP request from a web browser, the event is queued for the event in the order in which it is generated. The event dispatcher sends each event from the event queue to a designated destination that receives the event and its data.

【0033】

According to various embodiments of the system and method according to the present invention, the web object system also includes a locking mechanism. This locking mechanism ensures that the web object makes the correct transitions between states and that the actions performed within the states are uninterrupted. This reduces the likelihood that data and / or actions will be corrupted by other actions, events and / or web objects. Thus, in various embodiments of the systems and methods of the invention, the locking mechanism makes it impossible for a web object to be interrupted by other events while changing state and / or performing an action. become. A web object can only process subsequent events after changing its state and / or completing the execution of that action. Web object state changes are therefore minimal so that they cannot be interleaved or interrupted by other events or state changes in the same web object or other web objects, and the data they relate to. , Must be completed as a whole. The run-time component of a web object in a system and method according to the present invention manages the details necessary to ensure that the web object does not have to implement it separately. To do.

【0034】

In various embodiments of the system and method according to the invention, the web object system provides a template that provides one or more external representations of a web object, for example a web page encoded in HTML. Also includes a creation system or device. The external representation of a web object can be persistent so that it does not need to be regenerated continuously. That is, only the web objects that need to be updated need to be regenerated, rather than the entire external representation being regenerated.

【0035】

In various embodiments of the system and method according to the invention, the web object system is larger and more complex from the individual web objects by combining the representations of the individual web objects into a larger representation. Can create parallel communication web objects.

【0036】

The web object system operations shown in Figure 9 are used by web object 7324 events and / or actions to update web object 7334, and conversely, web object 7334 causes web object 7324 events and / or actions. It is the same as the operation of the web object system described above with respect to FIG. 8, except that it is used for updating. To avoid contention and race conditions when the state machine of one web object reads or writes data in another web object, the runtime support circuit, routine or management program 7350 Event processing is managed by web objects 7324 and 7334.

【0061】

Also, the displayed object 7522 generated by the web client 7540 may be different from the displayed object 7523 generated by the web client 7550. For example, the information requested by each of the web clients 7540 and 7550 may be different. In addition, the displayed objects 7522 and 7523 may differ in appearance and content, as templates 7322 and 7332 may be anchored and different by web objects 7324 and 7334, respectively.
