Modeling Pointcuts

Modeling pointcuts, i.e., modeling the places where to crosscut and/or the conditions under which to cross cut, is a principal task in aspect-oriented modeling. It is a fairly independent design issue and can be accomplished separate from other modeling tasks such as modeling the crosscutting effects. Modeling pointcuts is basical ly bout modeling selection queries. It requires novel model ing means. This paper gives a short overview on a new graphical approach to model pointcuts. It presents its semantics using OCL code. It presents its use in th e early aspect phase, and it demonstrates its capabilities o capture the pointcut semantics of prevailing aspect oriented programming techniques with help of exampl es.
