Abstract

A system and method for interacting with an object is provided. The system includes a method call interceptor that intercepts a method call made on an object and that routes the method call to a proxy. The method call interceptor is accessible to application code. The system also includes an application code generic proxy that after overriding a base class invocation method can receive intercepted method calls, can invoke methods on the object that the proxy images, can receive results from the object that the proxy images and can pass results to the entity that generated the intercepted method call.

Claims

1. A system that facilitates interaction with an object, comprising:

an application code accessible method call interceptor that receives a method call to an object and routes the method call to a proxy; and

a generic proxy that upon receipt of the method call invokes a method on the object, receives results from the object and passes the results to a calling entity.

2. The system of claim 1, the application code accessible method call interceptor populates a data store with data associated with the received method call.

3. The system of claim 2, the data store accessible by the generic proxy.

4. The system of claim 2, the data store populated with one or more of a method name, at least one input parameter, an input parameter count, at least one type identifier associated with the at least one input parameter, a return parameter count, at least one type identifier associated with returned parameters, method data that defines class/interface, a stack pointer and a heap pointer.

5. The system of claim 2, the data store is a message object that can be serialized and passed to a disparate domain.

6. The system of claim 1, the generic proxy performs proxy pre-processing prior to invocation of the method on the object.

7. The system of claim 6, proxy pre-processing comprises one or more of load-balancing, transaction processing, object migration, object persisting, remote method call monitoring, caching remote and local data, controlling remote method call invocations and optimization of remote call invocation by utilization of one or more neural network paradigms.

8. The system of claim 7, the one or more neural network paradigms comprise at least one of directed search networks, radial basis functions, cerebella model arithmetic computer and function link networks.

9. The system of claim 1, the generic proxy performs proxy post-processing subsequent to receipt of the results from the object.

10. The system of claim 9, proxy post-processing comprises one or more of auditing, transaction processing, object migration, object persisting, remote method call monitoring, caching remote and local data and optimization of remote call invocation by utilization of one or more training systems and methods.

11. A method that facilitates interaction with an object, comprising:

intercepting a method call on the object;

routing the method call to a generic proxy;

invoking a method on the object;

receiving a first result from the object; and

returning a second result to a calling entity.

12. The method of claim 11, further comprising generating a generic proxy from a base class proxy object.

13. The method of claim 12, further comprising overriding a base class method defined in the base class proxy object, the overridden base class method receives the intercepted method call.

14. The method of claim 11, further comprising populating a data store associated with the method call with information related to the method call.

15. The method of claim 14, the generic proxy accesses the data store associated with the method call to retrieve information related to the method call.

16. The method of claim 11, the generic proxy performs pre-processing prior to invoking the method on the object

17. The method of claim 11, the generic proxy performs post-processing after receiving the first result from the object.

18. The method of claim 11, the generic proxy utilizes one or more training systems and methods to optimize remote call invocation.

19. The method of claim 18, the one or more training systems and methods comprise at least one of back propagation, Bayesian, fuzzy sets and non-linear regression.

20. A system that facilitates interaction with an object, comprising:

means for intercepting a method call;

means for transferring control to an overridden base class method in a generic proxy;

means for routing the method call to the generic proxy;

means for invoking a method on the object; and

means for returning a result to a calling entity.
