    abstract = {We describe a generic Java framework that implements the software design pattern "visitor" and that is formally specified in the Java Modeling Language (JML). In addition to the information provided by a typical UML specification of the pattern, the JML specification describes the the sequence of visited objects in the order in which they are visited. A visitor may then specify its concrete behavior with respect to this sequence.},
