An Object-Based AOP Model and Its Implementation

The class-based AOP language, like AspectJ, weaves aspect into the class at the compile-time, and has achieved extension of the class behaviors at the compile-time. Sometimes, it is necessary to achieve behavior extension of a single object, not all of the objects belonging to the same type. We have obtained the inspiration from the role modeling, and proposed an object-based AOP model, which takes aspect as a role and generates instance of the aspect at the runtime, to achieve dynamic extension of the object behaviors through the dynamic binding between the objects and aspect instances.
