4. Together with filter_view, I'd like to have 'filter' function, so that I can do something like:
for_each( filter(vertices(g), boost::lambda::bind(out_degree_f, _1, g) == 0), .....);
Is it possible add such functions?
I guess you're using for_each from sequence_algo?
Right.
d:\boost-sandbox\boost\sequence_algo\container_traits.hpp(507) : fatal error C1507: previous user errors and subsequent error recovery halt further compilation
Wow. I'm afraid I don't have the time to fix that.
I guess gcc won't crash in this way ;-) What do you think about such functions in general. I might have the time to play with the idea.
It sure would be worthwhile to play with this idea. In your example above, filter() means something like make_filter_view() (I'd prefer the later, longer name), and such make_... functions should be provided for each view type.
BTW, please find a trivial patch to add some missing typenames. Could it be applied?
Applied. Please feel free to commit similar trivial patches whenever needed. - Roland
