Method Detail

• gatherRelations

  public static Set<OsmRelation> gatherRelations(OsmRelation relation,
                                                 OsmEntityProvider resolver)

  Given a relation find all referenced relations. Recursively repeat until no more relations are found. Return a set containing all these relations (including the original one) TODO: this version is only using child-regions one level nested

• gatherWays

  public static MultiSet<OsmWay> gatherWays(Set<OsmRelation> relations,
                                            OsmEntityProvider resolver)

  Gather all ways referenced by this set of relations.

• gatherWays

  public static Set<OsmWay> gatherWays(OsmRelation relation,
                                       OsmEntityProvider resolver)

  Gather all ways referenced by this relation.

• gatherNodes

  public static Set<OsmNode> gatherNodes(Set<OsmWay> ways,
                                         OsmEntityProvider resolver)

• gatherNodes

  public static Set<OsmNode> gatherNodes(OsmWay way,
                                         OsmEntityProvider resolver)

• buildRings

  public static List<WayRing> buildRings(MultiSet<OsmWay> ways,
                                         CountingMultiValMap<Long,OsmWay> wayTailMap)
                                  throws EntityNotFoundException

  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.

  Throws:

  EntityNotFoundException

• buildWayTailMap

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

  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.

  Throws:

  EntityNotFoundException

• checkRings

  public static boolean checkRings(Collection<WayRing> rings,
                                   OsmEntityProvider resolver)
                            throws EntityNotFoundException

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

  Returns:

  whether all rings are closed.

  Throws:

  EntityNotFoundException

                                              OsmEntityProvider resolver)
                                       throws EntityNotFoundException

  Throws:

  EntityNotFoundException
