dump()¶
Return a three-tuple of lists describing the Automaton as a graph of nodes, edges, failure links.
nodes: each item is a pair (node id, end of word marker)
edges: each item is a triple (node id, label char, child node id)
failure links: each item is a pair (source node id, node if connected by fail node)
For each of these, the node id is a unique number and a label is a number.
