Helloooooo Everybody !! The subject is not very clear, but given a few more lines I can make it a bit more explicit. Here is my problem :
When #11880 we will have in Sage a database of graph classes. That is objects representing things like "Interval Graphs", "Planar Graphs", things like that. This database contains a HUGE number of classes (around 1000), and some of these graph classes are more famous than others. In particular, we have in Sage algorithms to tests whether a graph is planar, or an interval graph. Hence it would be nice to be able to use these methods like that : g in graph_classes.PlanarGraphs g in graph_classes.IntervalGraph To do so, the recognition methods should be reached by the __in__ method of each of those graph classes. And here is where the problem lies : I have on one hand a way to build Sage objects representing graph classes, and on the other hand recognition algorithms for SOME of them. How should I make the link between the two ? 1) Should any object representing a Graph class have a __in__ method which checks whether the class represented by the object has a recognition algorithm listed in a.... dictionnary somewhere ? 2) Should the graph classes objects be generated in such a way (how ?) such that its __in__ method is automatically the good one ? I expect you already had to deal with problems like that in your code, so just in case you already found a great answer to that..... ;-) Thank youuuuuuuu !!!
