This is the traits class that produces the type for a <a
href="../../property_map/property_map.html">property map</a> object
for a particular graph type. The property is specified by the <a
href="./PropertyTag.html">PropertyTag</a> template parameter. Graph classes
must specialize this traits class to provide their own implementation
for property maps.
<pre>
template <class Graph, class PropertyTag>
struct property_map {
typedef ... type;
typedef ... const_type;
};
</pre>

The (mutable) property map type for mapping vertex or edge desriptors of
the graph to their associated property values, where the property is
specified by <tt>PropertyTag</tt>. This type is a <a

The (non-mutable) property map type for mapping vertex or edge
