[Boost-users] Regarding property maps

Hi all, I have been working on a graph using boost graph library with edge properties as bundled properties.I have the following struct as my edge property, typedef struct Edge{ int id; int source; int target; float cost; float reverse_cost; } Edge; 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.
