METHODS AND APPARATUS PROVIDING A CATEGORICAL APPROACH TO VALUETYPE BRIDGE SUPPORT

A system provides categorical mapping of valuetypes by receiving, as input, a valuetype within an object model specification. The system applies a categorical-based generator that applies at least one morphism to the object model specification. Application of the categorical-based generator generates an interface that exposes the valuetype in an interface object model and generates an implementation of the interface that exposes the valuetype in a middleware implementation object model. The interface and its implementation seamlessly support valuetype properties including inheritance, null values, native casting and arbitrary graph communication.
