Abstract
Modeling protean objects, i.e. objects adapting their structure and behavior dynamically with respect to changeable environment, may be challenging in traditional object oriented languages. While some dynamic languages make the implementation of changeable behavior of objects possible by injecting code into the objects at run-time, their lack of an in-depth compile-time code analysis makes the resulting code fragile. The concept of object metamorphism (OM) targets the gap between the two language types by introducing a declarative modeling of protean objects. Such a model, which is validated at compile-time, defines all possible compositions of a given object from smaller parts represented by traits. The actual composition used to instantiate the object is chosen dynamically with respect to the current environment. The result of this research will provide the theoretical concept of OM along with a proof-of-concept adoption of OM to Scala.
