Hi!
I'll assume you aren't talking about const/non-const since that can be done with an overload.
As a matter of fact, there is. I added a framework for compile-time mutability properties of graphs that (kind of) parallels the mutability concepts (in graph_concepts, not the documentation), Basically, it assigns tag classes to graphs based on their ability to add and remove vertices and edges with or without properties.
You can specialize the graph_mutability_traits for your derived type. There are also a number of metafunctions, graph_has_remove_vertex and is_mutable_graph.
The mutability traits aren't actually used outside the BGL tests. They could be, but there aren't really that many generic mutating algorithms.
Naturally, it's all undocumented :)
This is what I was looking for! Thanks! I really have to reexplore the files and not only rely on the documentation... Another issue: My custom graph seems to work quite nice, but my application slowed down by a factor of 10 or something similiar. The reason is, at least as I understand, that my vertex_descriptor is now an array which is costly to copy around. However, the vertex_descriptors are passed almost everywhere by value such that the structure gets copied over and over resulting in the performance degradation. Is there a simple trick to avoid this? It would be very helpful if tere is an easy way...
Thanks for the hint of the quickbook documents in the trunk - I went
through the process of generating the docs and there is a slight typo in the qbk-files: It fails to compile the stuff since it assumes the examples to be in the directory examples, but they are in the example (singular) directory. A symlink solved it for me, but it ought to be corrected.
Still working on it. I think I merged all of the quickbook examples into the example directory and forgot to update the links.
Thought you'd like to know...
Still the vertex_all stuff would be nice to know about. Any hint would be great.
I'll look into it.
Looking forward to it. Sebastian
