cloneMap<K, V> method

@override Map<K, dynamic> cloneMap<K, V>(Map<K, V> source)

Clones a Map with dynamic values, enforcing nesting depth limit.

Throws LimitExceededException if the nesting limit is exceeded.

Implementation

@override
Map<K, dynamic> cloneMap<K, V>(Map<K, V> source) {
  if (_nestIndex > nestLimit) {
    throw LimitExceededException('depth', _nestIndex);
  }
  _nestIndex++;
  try {
    return super.cloneMap<K, V>(source);
  } finally {
    _nestIndex--;
  }
}
