Hey alex, Thanks a lot for the reply.That worked for me.But can you help me understand the following in your code, 1.Second argument of the constructor, member_property_map(Map map, Type bundle_type::* member) : m_map(map), m_member(member) {} 2.What does the put_get_helper class actually do? Thanks in advance. On Tue, Sep 22, 2015 at 5:44 PM, alex <alexhighviz@hotmail.com> wrote:

Provided that I am inserting the data correctly,how do I get a property map for each of the elements of the struct,that is a property map for id,a property map for the source and so on.And moreover I also want to know how to extract the type of property map,as it is required to pass its type to other function as a template parameter.
Thanks in advance.
I had the same problem and developed a member_property_map to access the member of a bundled map.
It allows the following:
typedef boost::vector_property_map<edge> bundle_map_type; typedef blink::member_property_map<bundle_map_type, float> cost_map_type;
bundle_map_type bundle_map; cost_map_type cost_map(bundle_map, &edge::cost);
See attached for the implementation and example.
