Most definitely. In the crosscutting macro I am proposing at (
http://www.heron-language.com/aspect-cpp.html ) we could add class invariant
tests to the BeforeFxn and AfterFxn of the aspect. We could then also have
precondition tests in the BeforeFxn and postcondition tests in the AfterFxn.
The only issue is that an aspect applies uniformally to a set of functions
(the set of join-points, known as the point-cut). In order to overcome this
we need to simply write a case statement in the BeforeFxn / AfterFxn on the
passed function name. I am currently working on a new more powerful model
that will make it easier to do design by contract using AOP.
