    • Field Detail

      • osmWaysWithMultiplePlanitLinks

        protected Map<Long,​Set<MacroscopicLink>> osmWaysWithMultiplePlanitLinks
        track osmways with multiple planit links if they are created due to circular ways or breaking of links. Only track globally when part of intermodal reader where follow up components require this information, otherwise it is locally discarded after use

      • planitNodesByLocation

        protected final Map<org.locationtech.jts.geom.Point,​Pair<Node,​de.topobyte.osm4j.core.model.iface.OsmNode>> planitNodesByLocation
        track the PLANit nodes created on this layer by their location (which reflects either an OSM node, or an auto-generated stop_location, not related to an osm node in the latter case, no osm node is available) so they can be collected when needed, for example when breaking planit links

      • originalLinkInternalAvailableLocations

        protected Map<org.locationtech.jts.geom.Point,​Pair<List<MacroscopicLink>,​de.topobyte.osm4j.core.model.iface.OsmNode>> originalLinkInternalAvailableLocations
        Mapping from locations (representing known OSM nodes or auto-generated PLANit nodes without OSM node, in the latter case, no OSM node is stored in the pair) to the links they are internal to. When initial parsing is done, we verify if any entry in the map contains more than one link in which case the two link intersect at a point other than the extremes and we must break the link. Also, in case any existing link's extreme node is internal to any other link, the link where this location is internal to must be split into two because a PLANit network requires all intersections of links to occur at the end or start of a link. Since during breaking of links, the mapping between known locations (osm nodes/auto-generated planit nodes) and planit links is no longer correct we use a separate mapping via osmWaysWithMultiplePlanitLinks to track how original osm ways (links) are now split allowing us to map any previously registered location to the correct planit link even after breaking of links
