Method, apparatus, and system for implementing view caching in a framework to support web-based applications

A method comprising:

• synchronizing a server-side object and a client-side object, wherein
• the synchronizing comprises
• receiving a request at a server, wherein
• the request is from the client-side object,
• the client-side object is executed on a client,
• the request is configured to indicate
• receipt by the client of a user request to switch to a view, and
• whether a layout of the view is stored in a cache at the client,
• the view is described by the layout,
• the layout is configured to be stored in the cache,
• the view is a display panel comprising an arrangement of applets to be displayed in the GUI, and
• the request comprises a remote procedure call (RPC) configured to invoke a method of the server-side object;
• determining whether the request indicates that the layout is not stored in the cache;
• and
• if the request indicates that the layout is not stored in the cache,
• retrieving the layout by
• causing an object manager of a server-side synchronization mechanism to manage the server-side object by
• invoking the method of the server-side object, wherein the object manager is executed on the server,
• generating a response comprising the layout, and
• sending the response to the client.

A computer program product comprising:

• a non-transitory computer-readable storage medium;
• and
• a plurality of instructions, executable on a computer system, configured to synchronize a server-side object and a client-side object, wherein
• said instructions are encoded in said non-transitory computer-readable storage medium, and
• the plurality of instructions comprise
• a first set of instructions, executable on said computer system, configured to receive a request at a server, wherein
• the request is from the client-side object,
• the client-side object is executed on a client,
• the request is configured to indicate
• receipt by the client of a user request to switch to a view, and
• whether a layout of the view is stored in a cache at the client,
• the view is described by the layout,
• the layout is configured to be stored in the cache,
• the view is a display panel comprising an arrangement of applets to be displayed in the GUI, and
• the request comprises a remote procedure call (RPC) configured to invoke a method of the server-side object,
• a second set of instructions, executable on said computer system, configured to determining whether the request indicates that the layout is not stored in the cache, and
• a third set of instructions, executable on said computer system, configured to, if the request indicates that the layout is not stored in the cache,
• retrieve the layout by
• causing an object manager of a server-side synchronization mechanism to manage the server-side object by
• invoking the method of the server-side object, wherein
• the object manager is executed on the server,
• generate a response comprising the layout, and
• send the response to the client.
