Class PathDetailsFromEdges

java.lang.Object

com.graphhopper.util.details.PathDetailsFromEdges

All Implemented Interfaces:

Path.EdgeVisitor

public class PathDetailsFromEdges
extends Object
implements Path.EdgeVisitor

This class calculates a PathDetail list in a similar fashion to the instruction calculation, also see InstructionsFromEdges.

This class uses the PathDetailsBuilder. We provide every edge to the builder and up to its internals we create a new interval, ie. a new PathDetail in the List.

                                                       int previousIndex)

Calculates the PathDetails for a Path. This method will return fast, if there are no calculators.

Parameters:

path -

weighting -

pathBuilderFactory - Generates the relevant PathBuilders

Returns:

List of PathDetails for this Path

public void next(EdgeIteratorState edge,
                 int index,
                 int prevEdgeId)
