Constructor Detail

LineIntIndex

public LineIntIndex(BBox bBox,
                    Directory dir,
                    String name)

Method Detail

loadExisting

public boolean loadExisting()

store

public void store(InMemConstructionIndex inMem)

query

public void query(BBox queryShape,
                  LocationIndex.Visitor function)

findEdgeIdsInNeighborhood

public void findEdgeIdsInNeighborhood(double queryLat,
                                      double queryLon,
                                      int iteration,
                                      IntConsumer foundEntries)

This method collects edge ids from the neighborhood of a point and puts them into foundEntries.

If it is called with iteration = 0, it just looks in the tile the query point is in. If it is called with iteration = 0,1,2,.., it will look in additional tiles further and further from the start tile. (In a square that grows by one pixel in all four directions per iteration).
