addValue method

@override Future<void> addValue(NodeValue value)

Add a key/value pair to the node.

Adds a K/V tuple to the node. The key must not exist prior adding.

Implementation

@override
Future<void> addValue(NodeValue value) async {
  await _init();
  if (await _getValue(value.key) != null) {
    throw StorageException(
        'value "${value.key}" does already exist in the node "$path"');
  }
  lastModified = DateTime.now().millisecondsSinceEpoch;
  value.lastModified = lastModified;
  _values[value.key] = value;
}
