Method Details

isTurnRestriction

public static boolean isTurnRestriction(ReaderRelation relation)

getRestrictedWayIds

public static long[] getRestrictedWayIds(ReaderRelation relation)

getViaNodeIfViaNodeRestriction

public static long getViaNodeIfViaNodeRestriction(ReaderRelation relation)

buildRestrictionTopologyForGraph

public static Triple<ReaderRelation,RestrictionTopology,RestrictionMembers> buildRestrictionTopologyForGraph(BaseGraph baseGraph,
 ReaderRelation relation,
 LongFunction<Iterator<com.carrotsearch.hppc.cursors.IntCursor>> edgesByWay)
                                                                                                      throws OSMRestrictionException

OSM restriction relations specify turn restrictions between OSM ways (of course). This method rebuilds the topology of such a relation in the graph representation, where the turn restrictions are specified in terms of edge/node IDs instead of OSM IDs.

Throws:

OSMRestrictionException - if the given relation is either not valid in some way and/or cannot be handled and shall be ignored

checkIfTopologyIsCompatibleWithRestriction

public static void checkIfTopologyIsCompatibleWithRestriction(RestrictionTopology g,
 String restriction)
                                                       throws OSMRestrictionException

Throws:

OSMRestrictionException

extractMembers

public static RestrictionMembers extractMembers(ReaderRelation relation)
                                         throws OSMRestrictionException

Throws:

OSMRestrictionException

buildRestrictionsForOSMRestriction

public static List<RestrictionSetter.Restriction> buildRestrictionsForOSMRestriction(BaseGraph baseGraph,
 RestrictionTopology topology,
 RestrictionType type)

Converts an OSM restriction to (multiple) single 'no' restrictions to be fed into RestrictionSetter
