This class represents an edge in a Graph.

Edge instances are hashable, iterable and thus are convertible to a tuple, which contains the source and target vertices.

Raises an exception This class cannot be instantiated from Python

Methods

is_valid	Returns True if the descriptor corresponds to an existing edge in the graph, False otherwise.
source	Returns the source of the edge (a Vertex instance).
target	Returns the target of the edge (a Vertex instance).

is_valid()

Returns True if the descriptor corresponds to an existing edge in the graph, False otherwise.

source()

Returns the source of the edge (a Vertex instance).

target()

Returns the target of the edge (a Vertex instance).
