[Boost-users] [BGL] documentation problem

Hi, Is it required for a readable property map to have operator[]? At least, that is not mentioned at http://www.boost.org/libs/property_map/ReadablePropertyMap.html , so I assume, operator[] is not required. At http://www.boost.org/libs/graph/doc/johnson_all_pairs_shortest.html it is documented that weight_map named parameter must be a model of a readable property map. At johnson_all_pairs_shortest.hpp, line 101 we have w[e2] = w1[*e]; which assumes that weight_map has operator []. Is the problem in the readable property map documentation, or in the johnson_all_pairs_shortest, or I am doing something wrong? -- Val Samko http://val.digiways.com
