....it is also possible to change the visit method name and to have di erent arguments. This solution is a simpli cation of the multi method approach that dynamically performs the search of the best method to apply. We have compared these two approaches by using a Java multi method implementation [7]. The performances are equivalent, but our approach is much easier to realize.

....techniques (e.g. visitor design pattern, aspect) thanks to its modular architecture and has generic visualization tools. Our visitor approach is strongly based on this research work [20] and very close to other developments [9,16,18] We essentially use a simpli ed version of the multi methods [7,19] instead of using accept methods. In this way, it is possible: to obtain much more readable visitor programs (i.e. without cast) thanks to the xpro le speci cations, to get a simple kind of adaptative programming [12,17] dedicated to our applications thanks to the tree traversal ....

We made some successful experiences of SmartTools components integration in third parties environment [17, 12, 8]. We also easily connected new components like XML parsers (Sax, Xerces) and some graphic components like a graph server based on the Koala Graphic toolbox [3] 3 Semantic Analysis within the SmartTools Framework For any tree manipulation, it is important to have a simple and powerful ....

....depth rst traversal for example. We have introduced a generic visitor concept to factorize identical behaviours applying to the nodes of a tree. With this technique we have dened one visitor only to graphically display the tree, for any language. We also use a Java MultiMethods implementation [12] to ll many deciencies [18, 19] due to the visitor implementation based on the Java reAEect APIs. Additionally with this technique, we gain lisibility without losing eOEciency. We use DOM (level 2) as Tree API where each node has the same type. In SmartTools we extend this behaviour by typing ....

....and same number of arguments. For a given context, a target object and a n uple of actual parameter types, our method resolution provides the corresponding most speci c method. In this paper, we focus on a new simple and ecient algorithm to nd this most speci c method, that is more ecient than [10] and surprisingly simple. Among the advantages of multi methods [5, 15] we are more concerned with their ability to simplify the speci cation of algorithms outside the objects they deal with [12, 17, 11] More precisely, in component based software development, where functionalities have to be ....
