Abstract

A method for packaging an object graph including receiving a usage variable specification that includes a set of usages each usage specifying an attribute of an object in the object graph, creating a transient object graph representation containing the attribute specified in the variable usage specification, and packaging the transient object graph representation.

Claims

1. A method for packaging an object graph, comprising:

receiving a usage variable specification that includes a set of usages each usage specifying an attribute of an object in the object graph;

creating a transient object graph representation containing the attribute specified in the variable usage specification; and

packaging the transient object graph representation.

2. The method of claim 1, wherein creating the transient object graph representation comprises identifying an object in the object graph whose attributes are specified in the variable usage specification.

3. The method of claim 2, wherein identifying the object in the object graph comprises receiving a root object in the object graph.

4. The method of claim 3, wherein identifying the object in the object graph further comprises using the root object to find a path to the objects whose attributes are specified in the variable usage specification.

5. The method of claim 2, wherein creating the transient object graph representation further comprises representing the object with the attribute specified in the variable usage specification.

6. The method of claim 5, wherein creating the transient object graph further comprises storing a represented object as a node of the transient object graph.

7. The method of claim 1, further comprising:

converting the transient object graph representation into a form suitable for transport over a network link.

8. The method of claim 1, further comprising:

converting the transient object graph representation into a form suitable for storage on a storage medium.

9. The method of claim 1, further comprising:

converting the transient object graph representation into a byte stream.

10. The method of claim 1, further comprising:

converting the transient object graph representation into a hash table.

11. The method of claim 10, further comprising:

converting the hash table into a byte stream.

12. The method of claim 1, further comprising:

representing the transient object graph representation in a structured language format.

13. The method of claim 1, further comprising:

representing the transient object graph representation in a compressed format.

14. The method of claim 1, further comprising:

representing the transient object graph representation in an encrypted format.

15. A method for packaging an object graph, comprising:

receiving a usage variable specification that includes a set of usages each usage specifying an attribute of an object in the object graph;

creating a transient object graph representation containing the attribute specified in the variable usage specification;

packaging the transient object graph representation; and

converting the transient object graph representation into a form suitable for transport over a network link.

16. A method for packaging an object graph, comprising:

receiving a usage variable specification that includes a set of usages each usage specifying an attribute of an object in the object graph;

creating a transient object graph representation containing the attribute specified in the variable usage specification;

packaging the transient object graph representation; and

converting the transient object graph representation into a form suitable for storage on a storage medium.

17. A transport packager, comprising:

means for receiving a usage variable specification that includes a set of usages each usage specifying an attribute of an object in the object graph;

means for creating a transient object graph representation containing the attribute specified in the variable usage specification; and

means for packaging the transient object graph representation.

18. A computer-readable medium having recorded thereon instructions executable by a processor, the instructions for:

receiving a usage variable specification that includes a set of usages each usage specifying an attribute of an object in the object graph;

creating a transient object graph representation containing the attribute specified in the variable usage specification; and

packaging the transient object graph representation.

19. The computer-readable medium of claim 18, further comprising:

instructions for converting each trimmed object into a form suitable for transport over a network link.

20. The computer-readable medium of claim 18, further comprising:

instructions for converting each trimmed object into a form suitable for storage on a storage medium.

21. A computer-readable medium having recorded thereon instructions executable by a processor, the instructions for:

receiving a usage variable specification that includes a set of usages each usage specifying an attribute of an object in the object graph;

creating a transient object graph representation containing the attribute specified in the variable usage specification;

packaging the transient object graph representation; and

instructions for converting each trimmed object into a form suitable for transport over a network link.

22. A computer-readable medium having recorded thereon instructions executable by a processor, the instructions for:

receiving a usage variable specification that includes a set of usages each usage specifying an attribute of an object in the object graph;

creating a transient object graph representation containing the attribute specified in the variable usage specification;

packaging the transient object graph representation; and

instructions for converting each trimmed object into a form suitable for storage on a storage medium.

23. A distributed system having a client and a server, comprising:

an object generator interposed between the client and the server, the object generator having a capability to trim an object graph such that the trimmed object graph contains only the attributes specified in a variable usage specification; and

means for converting the transient object graph representation into a form suitable for transport over a network link between the client and the server.

24. An apparatus for packaging an object graph, comprising:

means for receiving a usage variable specification that includes a set of usages each usage specifying an attribute of an object in the object graph;

means for creating a transient object graph representation containing the attribute specified in the variable usage specification; and

means for packaging the transient object graph representation.
