Is it possible to convert other Property Maps to Vector Property Map?
My requirement is that the property map should be able to grow/expand (as I am using it with a dynamic graph which also grows). But I want to make it generic so that it works for any kind of property map. So I think if I am able to convert any type of property map to vector property map then I can grow the property map, when I add new vertices to the graph.
Hi Manas, I don't think it's possible in general, just because Property Map does not provide any method to iterate over elements. In the likely case that you have the list of vertices, you can try the following: ...... pm = ....... vector_property_map<unsigned> vpm; BGL_FORALL_VERTICES(v, g, Graph) { vpm[v] = pm[v]; } (the BGL_FORALL_VERTICES macro is defined in <boost/graph/iteration_macros.hpp>) - Volodya
