Returns:

the number of immediate predecessor Nodes of this Node in the Graph.

getSuccNodes

Iterator<? extends T> getSuccNodes(T N,
 U label)

Return an Iterator over the immediate successor nodes of this Node in the Graph on edges with some label.

This method never returns null.

Returns:

an Iterator over the immediate successor Nodes of this Node.

getSuccLabels

Iterator<? extends U> getSuccLabels(T N)

Returns:

the labels on edges whose source is N

getSuccNodeCount

int getSuccNodeCount(T N,
 U label)

Return the number of immediate successor nodes of this Node in the Graph
