class Graph.Vertex

Implements the protocols.LabelledGraph.Vertex protocol. Additionally, the id is in the range \([0, numVertices[\).

class Graph.Edge

Implements the protocols.LabelledGraph.Edge protocol.

class Graph.VertexRange

Implements the protocols.Graph.VertexRange protocol, in addition to the following functionality.

__getitem__(i)

Returns

the ith vertex of the graph.

Return type

Graph.Vertex

class Graph.EdgeRange

Implements the protocols.Graph.EdgeRange protocol.

class Graph.IncidentEdgeRange

Implements the protocols.Graph.IncidentEdgeRange protocol.
