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.

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.
