FRAMEWORK FOR MARSHALING AND UNMARSHALING ARGUMENT OBJECT REFERENCES

Methods and devices for reducing computing overhead in a distributed client/server based computing system which utilize an efficient framework for marshaling and unmarshaling argument object references are disclosed. In one aspect of the invention, a method of unmarshaling an argument object reference, which includes a subcontract identifier, that is a part of an argument encapsulated within a marshal buffer involves identifying the subcontract identifier associated with the argument object reference, using the identified subcontract identifier to identify an appropriate associated unmarshal method, and calling the associated unmarshal method. In another aspect of the invention, a method of marshaling an argument object reference, which includes a subcontract identifier, that is a part of an argument encapsulated within a marshal buffer involves invoking a marshal method of a client representation in the argument object reference passing the marshal buffer as an argument to the marshal method.
