Interface NodeAccess

All Superinterfaces:

PointAccess

public interface NodeAccess
extends PointAccess

This interface specifies how to access properties of the nodes in the graph. Similar to EdgeExplorer as it needs multiple instances for different threads or loops but without the need for an additional iterator.
