cloneMapTyped<K, V> method

@override Map<K, V> cloneMapTyped<K, V>(Map<K, V> source)

Return a typed Map<K, V> with values deep-cloned.

Keys are reused as-is (not cloned). Values are deep-cloned. Preserves the concrete Map implementation (e.g. LinkedHashMap, HashMap, UnmodifiableMapView). Throws UnsupportedTypedCloneException if a nested plain Map is encountered during typed cloning.

Implementation

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