A graph-container-directed-edge is both a directed-edge-mixin and a graph-container-edge.
| directed-edge-mixin | This mixin class is used to indicate that an edge is directed. |
|---|---|
| graph-container-edge | This is the root class for edges in graph-containers. It adds vertex-1 and vertex-2 slots. |
| color | The `color` is used by some algorithms for bookkeeping. [?? Should probably be in a mixin] Initargs::color; Accessors:color. |
|---|---|
| edge-id | The `edge-id` is used internally by CL-Graph for bookkeeping. Initform:0, Initargs::edge-id; Accessors:edge-id. |
| element | Initargs::element,:value; Accessors:element, value. |
| graph | The `graph` of which this edge is a part. Initargs::graph; Reader:graph. |
| tag | The `tag` is used by some algorithms for bookkeeping. [?? Should probably be in a mixin] Initargs::tag; Accessors:tag. |
| vertex-1 | `Vertex-1` is one of the two vertexes that an edge connects. In a directed-edge, `vertex-1` is also the `source-edge`. Initargs::vertex-1; Reader:vertex-1. |
| vertex-2 | `Vertex-2` is one of the two vertexes that an edge connects. In a directed edge, `vertex-2` is also the `target-vertex`. Initargs::vertex-2; Reader:vertex-2. |
| add-edge | Add-edge adds an existing edge to a graph. As |

| add-edge-to-vertex | Attaches the edge |

| dfs-cross-edge-p | |
| dfs-edge-type | |
| dfs-forward-edge-p | |
| dfs-tree-edge-p | |
| directed-edge-p | Returns true if-and-only-if edge is directed |
| edge->dot | Used by graph->dot to output edge formatting for |
| edge-lessp-by-direction | Returns true if and only if edge-1 is undirected and edge-2 is directed. |
| edge-lessp-by-weight | Returns true if the weight of edge-1 is strictly less than the weight of edge-2. |
| find-edge | Search |
| find-vertex | Search 'graph' for a vertex with element |
| find-vertex-if | Returns the first vertex in |
| iterate-vertexes | Calls |
| other-vertex | Assuming that the value-or-vertex corresponds to |
| out-edge-for-vertex-p | Returns true if the edge is connected to vertex and |
| source-vertex | Returns the source-vertex of a directed |
| tagged-edge-p | Returns true if-and-only-if edge's tag slot is t |
| target-vertex | Returns the target-vertex of a directed |
| undirected-edge-p | Returns true if-and-only-if edge is undirected |
| untagged-edge-p | Returns true if-and-only-if edge's tage slot is nil |
| vertexes | Returns a list of the vertexes of |
| weight | Returns the weight of an edge. This defaults to 1.0 |
