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

public static List<ChainOfNodes> convertToSegmentRings(List<ChainOfWays> rings)

closeUnclosedRingWithStraightLine

public static void closeUnclosedRingWithStraightLine(Collection<ChainOfWays> rings)

convertToSegmentChainsAndResolveNodeIntersections

public static void convertToSegmentChainsAndResolveNodeIntersections(List<ChainOfWays> chains,
                                                                     List<ChainOfNodes> outRings,
                                                                     List<ChainOfNodes> outNonRings)
