Transport independent invocation and servant interfaces that permit both typecode interpreted and compiled marshaling

A server invocation object for use in executing a method call in a distributed operating environment that utilizes an object request broker for facilitating communications between different objects, the server invocation object comprising:

• a first identifier arranged to identify a marshal buffer associated with the server invocation object;
• a second identifier arranged to identify a method descriptor associated with the server invocation object;
• and
• a third identifier pointer arranged to identify an invocation descriptor associated with the server invocation object, the invocation descriptor identifying at least one associated parameter descriptor, the at least one associated parameter descriptor being arranged to describe the characteristics associated with a parameter.

• a second identifier arranged to identify a method descriptor associated with the server invocation object;
• a third identifier pointer arranged to identify an invocation descriptor associated with the server invocation object, the invocation descriptor identifying marshal and unmarshal methods which are arranged to call a generic marshal method to unmarshal arguments included in the invocation descriptor and to call a generic unmarshal method to unmarshal the arguments included in the invocation descriptor;
• and
• a fourth identifier arranged to identify a context associated with the server invocation object, wherein the context includes a list of associations for a method associated with the method descriptor.
