Parameter | Description |
---|---|
Graph | The graph type whose associated types are being accessed. |
Member | Description |
---|---|
vertex_descriptor | The type for the objects used to identity vertices in the graph. |
edge_descriptor | The type for the objects used to identity edges in the graph. |
adjacency_iterator | The type for the iterators that traverse the vertices adjacent to a vertex. |
out_edge_iterator | The type for the iterators that traverse through the out-edges of a vertex. |
in_edge_iterator | The type for the iterators that traverse through the in-edges of a vertex. |
vertex_iterator | The type for the iterators that traverse through the complete vertex set of the graph. |
edge_iterator | The type for the iterators that traverse through the complete edge set of the graph. |
directed_category | This says whether the graph is undirected (undirected_tag) or directed (directed_tag). |
edge_parallel_category | This says whether the graph allows parallel edges to be inserted (allow_parallel_edge_tag) or if it automatically removes parallel edges (disallow_parallel_edge_tag). |
traversal_category | The ways in which the vertices in the graph can be traversed. The traversal category tags are: incidence_graph_tag, adjacency_graph_tag, bidirectional_graph_tag, vertex_list_graph_tag, edge_list_graph_tag, adjacency_matrix_tag. You can also create your own tag which should inherit from one or more of the above. |
vertices_size_type | The unsigned integer type used for representing the number of vertices in the graph. |
edges_size_type | The unsigned integer type used for representing the number of edge in the graph. |
degree_size_type | The unsigned integer type used for representing the degree of vertices in the graph. |
