Method Summary

Modifier and Type	Method and Description
double	getTurnCost(long flags)
long	getTurnFlags(boolean restricted, double costs)
boolean	isTurnRestricted(long flags)

Method Detail

isTurnRestricted

boolean isTurnRestricted(long flags)

Returns:

true, if the turn restriction is encoded in the specified flags

getTurnCost

double getTurnCost(long flags)

Returns:

the costs encoded in the specified flag, if restricted it will be Double.POSITIVE_INFINITY

getTurnFlags

long getTurnFlags(boolean restricted,
                  double costs)

Parameters:

restricted - true if restricted turn, equivalent to specifying costs = Double.POSITIVE_INFINITY

costs - the turn costs, specify 0 or Double.POSITIVE_INFINITY if restricted == true. Only used if restricted == false.

Returns:

the encoded flags
