| basic-edge | This is the root class for all edges in CL-Graph. |
|---|
| 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:value, element. |
| 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. |
| add-edge | Add-edge adds an existing edge to a graph. As add-edge-between-vertexes is generally more natural... |
|---|---|
| add-edge-to-vertex | Attaches the edge `edge` to the vertex `vertex`. |
| delete-edge | Delete the `edge' from the `graph' and returns it. |
| directed-edge-p | Returns true if-and-only-if edge is directed |
| edge->dot | Used by graph->dot to output edge formatting for `edge` onto the `stream`. The function can assum... |
| 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-vertex | Search 'graph' for a vertex with element 'value'. The search is fast but inflexible because it us... |
| find-vertex-if | Returns the first vertex in `thing` for which the `predicate` function returns non-nil. If the `k... |
| iterate-vertexes | Calls `fn` on each of the vertexes of `thing`. |
| out-edge-for-vertex-p | Returns true if the edge is connected to vertex and is either an undirected edge or a directed ed... |
| tagged-edge-p | Returns true if-and-only-if edge's tag slot is t |
| 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 |
| weight | Returns the weight of an edge. This defaults to 1.0 and can only be altered if the edge is a sub-... |
