Abstract
A system for creating before and after behavior upon invocation of a method in an object-oriented system. The framework provides metaclasses containing methods for dispatching a before method and an after method at the time of invocation of each client method in subclass instances. Object-oriented system properties of inheritance and encapsulation are supported as are derived metaclasses. Derivation ensures that the specification syntax for each class does not impact the expected result. The combination of explicit before after classes, dispatcher class, and derived metaclasses ensures that the system will have associative composition.
