Constructor Detail

OSMTurnRelationParser

public OSMTurnRelationParser(String name,
                             int maxTurnCosts,
                             List<String> restrictions)

Parameters:

maxTurnCosts - specify the maximum value used for turn costs, if this value is reached a turn is forbidden and results in costs of positive infinity.
