use of com.graphhopper.routing.util.AllEdgesIterator in project graphhopper by graphhopper.

the class GHUtility method createSortedGraph.

    AllEdgesIterator eIter = fromGraph.getAllEdges();
    while (eIter.next()) {
        int base = eIter.getBaseNode();

Example 7 with AllEdgesIterator

use of com.graphhopper.routing.util.AllEdgesIterator in project graphhopper by graphhopper.

the class GHUtility method copyTo.

/**
     * @return the specified toGraph which is now filled with data from fromGraph
     */
// TODO very similar to createSortedGraph -> use a 'int map(int)' interface
public static Graph copyTo(Graph fromGraph, Graph toGraph) {
    AllEdgesIterator eIter = fromGraph.getAllEdges();
    while (eIter.next()) {
        int base = eIter.getBaseNode();
        int adj = eIter.getAdjNode();
        eIter.copyPropertiesTo(toGraph.edge(base, adj));
    }
    NodeAccess fna = fromGraph.getNodeAccess();
    NodeAccess tna = toGraph.getNodeAccess();
    int nodes = fromGraph.getNodes();
    for (int node = 0; node < nodes; node++) {
        if (tna.is3D())
            tna.setNode(node, fna.getLatitude(node), fna.getLongitude(node), fna.getElevation(node));
