Abstract

An environment for developing clientside/serverside code is disclosed. The environment supports the perception that the server space and client space are seamlessly joined into a single program execution space. An outgrowth of the single execution space includes effective event handling on the server through enabling created objects to migrate effectively between the server and client.

Claims

a memory for storing code;

a first processor on said first machine for executing said code and instantiating an object on said first machine;

an output for outputting said instantiated object with persistence information from said first machine to said second machine;

wherein, after said instantiated object is output from said first machine, said first processor deletes the instantiation of said object from said first machine.

2. The system according to claim 1, further comprising:

a second processor on said second machine for receiving said instantiated object with said persistence information and creating events based on interaction with said object that effect said persistence information, wherein said persistence information includes information identifying said instantiated object, and wherein upon creating said events said persistence information is transported from said second machine to said first machine.

3. The system of claim 1 wherein

the memory stores code and a page, said page comprising objects;

the first processor instantiates at least one of said objects from said page in said first machine to create a first instantiated object on said first machine, said first instantiated object containing stored property information;

the outputting outputs said first instantiated object with persistence information on the first machine from the first machine to said second machine so that the first instantiated object on said second machine is an instantiated object having said persistence information, said persistence information describing a property of said property information of said first instantiated object.

4. The system according to claim 3, further comprising:

a second processor on said second machine for receiving said first instantiated object from said first machine after said first instantiated object on said first machine is output from said first machine to said second machine with said persistence information and creating an event upon interaction with said first instantiated object, wherein said persistence information includes information identifying said instantiated object, and wherein said event and said persistence information are transported from said second machine to said first machine.

5. A system for manipulating objects received at a first machine from a second machine rendering a page, comprising:

an input in said first machine for receiving persistence information that includes information identifying an instantiated object and an event from said second machine;

a processor in said first machine for reinstantiating said object based in part on said received persistence information;

an event handler in said first machine for handling said event in combination with modifying said persistence information;

an output for outputting said reinstantiated object with said modified persistence information to said second machine.

6. The system of claim 5 wherein

said persistence information received at said input identifies an object instantiated on said second machine;

the processor creates an instantiated object on the first machine by instantiating the object on the first machine, said instantiated object on the first machine corresponding to said object instantiated on said second machine.

7. A method for transporting objects between a first and second machine where said first machine is programmed in a first language and said second machine is programmed in a second language, said method comprising the steps of:

storing a code in a memory;

executing said code in a first processor on said first machine;

instantiating an object on said first machine;

outputting said instantiated object with persistence information from said first machine to said second machine;

deleting said object from said first machine after said object is output from said first machine.

8. The method of according to claim 7, further comprising the steps of:

receiving said instantiated object with said persistence information at a second processor on said second machine and

creating events based on interacting with said instantiated object, wherein said persistence information includes information identifying said instantiated object, and wherein upon creating said events said persistence information is transported from said second machine to said first machine.

9. The method of claim 7 wherein said persistence information describes a property of said object.

10. The method of according to claim 9, further comprising the steps of:

receiving said object with said persistence information at a second processor on said second machine and

interacting with said object, said interaction creating an event, said event describing a modification of said object, wherein said persistence information includes information identifying said object, and wherein said event and said persistence information are transported from said second machine to said first machine.

11. A method for manipulating an object received at a first machine from a second machine rendering a page, comprising the steps of:

receiving at a first machine persistence information including information identifying an instantiated object and an event from said second machine;

reinstantiating said object based in part on said received persistence information;

handling said event in combination with modifying said persistence information;

outputting said reinstantiated object with said modified persistence information to said second machine.

12. The method of claim 11, said persistence information describing a property of said object, wherein the reinstantiating step comprises reinstantiating said object based in part on said persistence information in said first machine, said handling step comprises handling said event in combination with modifying said property of said object, said property being modified in said first machine, and said outputting step comprises outputting said persistence information including said modified property from said first machine to said second machine.

13. The method of claim 11 wherein

said receiving step comprises receiving at a first machine persistence information and an event from said second machine, said persistence information describing a property of an object instantiated on said second machine;

said reinstantiating step comprising reinstantiating said instantiated object having said property in said first machine based in part on said persistence information received from said second machine to create a second reinstantiated object on said first machine, said second reinstantiated object on said first machine corresponding to said instantiated object having said property on said second machine;

said handling step comprising handling said event in combination with modifying said property on said first machine to create modified persistence information on said first machine;

said outputting step comprising outputting said second reinstantiated object with said modified persistence information from said first machine to said second machine.
