cloneMap<K, V> method

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

Deep-clones an untyped Map<K, dynamic> with circular reference detection.

Throws CircularReferenceCloneException if a circular reference is detected.

Implementation

@override
Map<K, dynamic> cloneMap<K, V>(Map<K, V> source) {
  _assertCircRef(source.hashCode);
  _nestIndex++;
  try {
    return super.cloneMap<K, V>(source);
  } finally {
    _nestIndex--;
  }
}
