end node fn (EndNodeFn)

A UnaryFunction that maps a GraphPath to the GraphNode that is the end of the GraphPath. Note that, unlike TerminalNodeFn (which relates a GraphArc to a GraphNode), EndNodeFn is a total function - every GraphPath has a end.

Se graph é un' istanza di Grafo e node1 é un' istanza di NodoDelGrafo e node2 é un' istanza di NodoDelGrafo e node1 é una parte di graph e node2 é una parte di graph e node1 is not uguale a node2, allora esiste arc,path tale che

graph é un' istanza di CircuitoDelGrafo se e solo se esiste node tale che "l' inizio di graph" is uguale a node e "la fine di graph" is uguale a node.
