@override
void addNode(Node node, {bool replaceIfExists = true}) {
  final row = _nodeToRow(node);
  if (replaceIfExists) {

    _db.execute('DELETE FROM node_properties WHERE nodeId = ?', [node.id]);
  }
  _db.execute(
    'INSERT INTO nodes '
    '(id, type, labelProperty, uniqueProperty, urlProperty, icon) '
    'VALUES (?, ?, ?, ?, ?, ?)',
    row,
  );
  _saveNodeProperties(node.id, node.properties);
