Method Detail

neighbours

public Collection<? extends V> neighbours(V node)

Description copied from interface: GraphModel

Return all nodes to which there is an edge from a given node. The order of nodes may or may not be significant to the application; it is ignored by all algorithms in this package. Multiple occurrences of the same node may or may not imply multiple edges, depending on the context.

A return value of null indicates that the given node object is not part of the graph covered by this graph model. A graph model is called closed iff neighbours(v).contains(w) implies neighbours(w) != null for all node objects v, w. All traversal algorithms require graph models to be closed.

Specified by:

neighbours in interface GraphModel<V extends Node<? extends V>>

Parameters:

node - a node

Returns:

a read-only collection containing all neighbours of node, or null if node is not a node of the graph represented by this model.
