|
This class provides an alternate method for accessing some of the
|
|
associated types of the <tt>adjacency_list</tt> class. The main reason
|
|
for this class is that sometimes one would like to create graph
|
|
properties whose values are vertex or edge descriptors. If you try to
|
|
use <tt>graph_traits</tt> for this you will run into a problem with
|
|
mutually recursive types. To get around this problem, the
|
|
<tt>adjacency_list_traits</tt> class is provided, which gives the user
|
|
access to the vertex and edge descriptor types without requiring the
|
|
user to provide the property types for the graph.
|
|
|
|
<pre>
|
|
template <class EdgeList, class VertexList, class Directed>
|
|
struct adjacency_list_traits {
|
|
typedef ... vertex_descriptor;
|
|
typedef ... edge_descriptor;
|
|
typedef ... directed_category;
|
|
typedef ... edge_parallel_category;
|
|
};
