Abstract

A method for dynamically casting an object graph, including creating an internal representation using a root object of the object graph, instantiating a cast object graph using a casting rule and the internal representation, and populating the cast object graph.

Claims

1. A method for dynamically casting an object graph, comprising:

creating an internal representation using a root object of the object graph;

instantiating a cast object graph using a casting rule and the internal representation; and

populating the cast object graph.

2. The method of claim 1, further comprising:

instantiating a cast object graph attribute using the casting rule and the internal representation.

3. The method of claim 1, further comprising:

retrieving the root object using a variable usage specification.

4. The method of claim 1, further comprising:

obtaining a class definition, wherein the class definition is used to create the internal representation.

5. The method of claim 4, wherein the class definition is generated at runtime by a transport packager.

6. The method of claim 1, wherein the casting rule comprises a casting method.

7. The method of claim 6, wherein the casting method implements a mapping method.

8. The method of claim 6, wherein the casting method implements a suffix method.

9. The method of claim 6, wherein the casting method implements a parser method.

10. The method of claim 1, wherein the internal representation is a serialized file.

11. A method for dynamically casting an object graph, comprising:

retrieving a root object of the object graph using a variable usage specification;

obtaining a class definition, wherein the class definition is used to create an internal representation;

creating the internal representation using the root object of the object graph;

instantiating a cast object graph using a casting rule and the internal representation;

populating the cast object graph; and

instantiating a cast object graph attribute using the casting rule and the internal representation.

12. A distributed computer system, comprising:

a client;

a server operatively connected to the client;

a client-side transport packager located on the client;

a server-side transport packager located on the server;

means for creating an internal representation using a root object of the object graph;

means for instantiating a cast object graph using a casting rule and the internal representation; and

means for populating the cast object graph.

13. The distributed computer system of claim 12, further comprising:

means for instantiating a cast object graph attribute using the casting rule and the internal representation.

14. The distributed computer system of claim 12, further comprising:

means for retrieving the root object using a variable usage specification.

15. The distributed computer system of claim 12, further comprising:

means for obtaining a class definition, wherein the class definition is used to create the internal representation.

16. The distributed computer system of claim 15, wherein the class definition is generated at runtime by a transport packager.

17. The distributed computer system of claim 12, wherein the casting rule comprises a casting method.

18. The distributed computer system of claim 17, wherein the casting method implements a mapping method.

19. The distributed computer system of claim 17, wherein the casting method implements a suffix method.

20. The distributed computer system of claim 17, wherein the casting method implements a parser method.

21. The distributed computer system of claim 12, wherein the internal representation is a serialized file.

22. A distributed computer system, comprising:

a client;

a server operatively connected to the client;

a client-side transport packager located on the client;

a server-side transport packager located on the server;

means for retrieving a root object of the object graph using a variable usage specification;

means for obtaining a class definition, wherein the class definition is used to create an internal representation

means for creating the internal representation using the root object of the object graph;

means for instantiating a cast object graph using a casting rule and the internal representation;

means for populating the cast object graph; and

means for instantiating a cast object graph attribute using the casting rule and the internal representation.

23. An apparatus for dynamically casting an object graph, comprising:

means for retrieving a root object of the object graph using a variable usage specification;

means for obtaining a class definition, wherein the class definition is used to create an internal representation;

means for creating the internal representation using the root object of the object graph;

means for instantiating a cast object graph using a casting rule and the internal representation;

means for populating the cast object graph; and

means for instantiating a cast object graph attribute using the casting rule and the internal representation.
