Strange... One last attempt, this time posting through the Yahoo
Groups interface and not directly to gmane.comp.lib.boost.user...
Sorry - my previous post got cut in half somewhere in transit. This
is a
reposting:
What determines when boost::get(Graph, vertex_myproperty_t) returns a
boost::property_map::type vs. a
::const_type?
Suppose:
enum vertex_myproperty_t { vertex_myproperty = 12345};
BOOST_INSTALL_PROPERTY(vertex,myproperty);
typedef property
vertex_properties_t;
typedef adjacency_list
graph_t;
typedef property_map::type
vertex_myproperty_map_t;
graph_t Graph;
vertex_myproperty_map_t MyMap = get(vertex_myproperty, Graph);
^--- this works as I expected. However, if I try to get a copy of my
property map this way inside a dfs visitor method, my compiler tells
me that
there's no suitable conversion from property_map::const_type to property_map::type (IA32 6.0 Intel compiler). For performance
reasons, I should probably just pass a reference the visitor on
construction
and be done with it for the duration of the algorithm. But why is the
compiler hassling me on this? What am I missing?
Thanks - Chris
