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), .....);
Just out of curiosity:
Why don't you use a transform_view instead of for_each()?
Well, I need to invoke a function on each element of filtered sequence, not transform it further.
Of course I don't know the details here (i.e. which function is meant by "....."),
It's going to be boost::lambda::bind(add_edge_f, _1, sink, g)
but wouldn't it be possible here to say
filter_view<Vertices, ...> filtered( vertices(g), bind(...) == 0 ); transform_view< filter_view<.,.>, ... > result( filtered, some_function() );
Do I have to iterate over 'result' to really invoke the function? - Volodya
