On-the-fly contextual adaptation with the RoleAdapter Pattern

The RoleAdapter Design Pattern allows using objects of any model as if they implemented any given programmatic interface, with contextual behavior. To achieve this, it makes objects from many basic building blocks of OOP, like methods, method signatures, interfaces, etc. This allows clients of a data model to define, at run-time, an interface for any data model they have to use. Objects encapsulating methods, defined independently for the model, are chosen and bound to the signatures included in the interface according to external configuration hints. Since the adaptation is done local to a context, different view instances can show different aspects of a complex model. The resulting composite definition of interface is similar in intent to that of subject-oriented programming, but achieved wholly within a traditional OOPL like Java
