How to use

getIndexInformation

method

in

org.janusgraph.diskstorage.Backend

private static void assertStorageExists(Backend backend, boolean exists) throws Exception {
  final String suffix = exists ? "should exist before clearing" : "should not exist after clearing";
  assertTrue("graph " + suffix, backend.getStoreManager().exists() == exists);
  for (final IndexInformation index : backend.getIndexInformation().values()) {
    assertTrue("index " + suffix, ((IndexProvider) index).exists() == exists);
  }
}

StoreFeatures storeFeatures = backend.getStoreFeatures();
this.indexSerializer = new IndexSerializer(configuration.getConfiguration(), this.serializer,
    this.backend.getIndexInformation(), storeFeatures.isDistributed() && storeFeatures.isKeyOrdered());
this.edgeSerializer = new EdgeSerializer(this.serializer);
this.vertexExistenceQuery = edgeSerializer.getQuery(BaseKey.VertexExists, Direction.OUT, new EdgeSerializer.TypedInterval[0]).setLimit(1);
