Building and maintaining the class hierarchy has been recognized as an important but one of the most difficult activities of object-oriented design. Concept (or Galois) lattices and variant structures are presented as a framework for dealing with the design and maintenance of class hierarchies. Because the design of class hierarchies is inherently an(More)
A tool for generating the interface hierarchy of a set of classes for the Smalltalk-80 library is described. The tool can be useful for analyzing the class library or simply for reuse purposes by providing an alternative view that is closer to the client's perspective than the inheritance hierarchy. The interface of each class to consider is extracted(More)
Female sexual mutilations result in an important physical and mental suffering. A large number of women have been affected and require a global management, including surgical clitoral transposition. This surgical technique is allowing a rapid improvement of clinical symptoms. In this article, we will describe the indications and operative technique of the(More)
