Constructor Detail

ExtendedNodeAccess

public ExtendedNodeAccess(NodeAccess nodeAccess,
                          PointList additionalNodes,
                          int firstAdditionalNodeId)

Parameters:

nodeAccess - the node access this class delegates to

additionalNodes - the additional points that should be used

firstAdditionalNodeId - the node id that is used for the first additional point (all other nodes will use consecutive ids)

Method Detail
