An example of persistence for a directed graph structure. The graph is stored as a collection of edges, each referencing both a "lower" and an "upper" node in a table of nodes. Basic persistence and querying for lower- and upper- neighbors are illustrated::
|
|
|
|
n2 = Node(2)
|
|
n5 = Node(5)
|
|
n2.add_neighbor(n5)
|
|
print n2.higher_neighbors()
