Method Details

calcEdgeMillis

public long calcEdgeMillis(EdgeIteratorState edgeState,
 boolean reverse)

Description copied from interface: Weighting

This method calculates the time taken (in milliseconds) to travel along the specified edgeState. It is typically used for post-processing and on only a few thousand edges.

Specified by:

calcEdgeMillis in interface Weighting

calcTurnWeight

public double calcTurnWeight(int inEdge,
 int viaNode,
 int outEdge)

Specified by:

calcTurnWeight in interface Weighting

calcTurnMillis

public long calcTurnMillis(int inEdge,
 int viaNode,
 int outEdge)

Specified by:

calcTurnMillis in interface Weighting

hasTurnCosts

public boolean hasTurnCosts()

Description copied from interface: Weighting

This method can be used to check whether or not this weighting returns turn costs (or if they are all zero). This is sometimes needed to do safety checks as not all graph algorithms can be run edge-based and might yield wrong results when turn costs are applied while running node-based.

Specified by:

hasTurnCosts in interface Weighting

toString

public String toString()
