Example 1 with CHStorage

use of com.graphhopper.storage.CHStorage in project graphhopper by graphhopper.

the class CHPreparationHandler method load.

public Map<String, RoutingCHGraph> load(GraphHopperStorage ghStorage, List<CHConfig> chConfigs) {
    Map<String, RoutingCHGraph> loaded = Collections.synchronizedMap(new LinkedHashMap<>());
    List<Callable<String>> callables = chConfigs.stream().map(c -> (Callable<String>) () -> {
        CHStorage chStorage = ghStorage.loadCHStorage(c.getName(), c.isEdgeBased());
        if (chStorage != null)
            loaded.put(c.getName(), ghStorage.createCHGraph(chStorage, c));
        else {
            // todo: this is ugly, see comments in LMPreparationHandler
            ghStorage.getDirectory().remove("nodes_ch_" + c.getName());
            ghStorage.getDirectory().remove("shortcuts_" + c.getName());
        }
        return c.getName();
    }).collect(Collectors.toList());
    GHUtility.runConcurrently(callables, preparationThreads);
    return loaded;
