# forEach method

void forEach (void f(K key, V value))
override

Applies `f` to each key/value pair of the map.

Calling `f` must not add or remove keys from the map.

## Implementation

    void forEach(void f(K key, V value)) {
      Iterator<_SplayTreeNode<K>> nodes = _SplayTreeNodeIterator<K>(this);
      while (nodes.moveNext()) {
        _SplayTreeMapNode<K, V> node = nodes.current;
        f(node.key, node.value);
      }
    }
