Method Detail

• buildRings

  public static List<ChainOfWays> buildRings(MultiSet<OsmWay> ways,
                                             CountingMultiValMap<Long,OsmWay> wayTailMap)

  Given a set of ways and their head's and tail's in the wayTailMap, construct valid rings by combining ways with same tail-ids.

• buildWayTailMap

  public static CountingMultiValMap<Long,OsmWay> buildWayTailMap(MultiSet<OsmWay> ways)

  For all ways given, build a multivalmap from node-ids to ways. Head and tail of each way are put as key and the way as value.

• checkRings

  public static void checkRings(Collection<ChainOfWays> rings,
                                OsmEntityProvider resolver,
                                MissingEntitiesStrategy missingEntitiesStrategy)
                         throws EntityNotFoundException

  For each ring in this collection of rings, check whether it is closed. If not, print some status information.

  Parameters:

  missingEntitiesStrategy -

  Throws:

  EntityNotFoundException

• convertToSegmentRings

• closeUnclosedRingWithStraightLine

  public static void closeUnclosedRingWithStraightLine(Collection<ChainOfWays> rings)

• convertToSegmentChainsAndResolveNodeIntersections
