RecursiveIterator<TKey, TValue> |
Iterates over a recursive iterator, using a callback to determine which items with children to descend into
Similar to {@see RecursiveCallbackFilterIterator}, but the callback is only used to filter the return value of {@see RecursiveIterator::hasChildren()}, allowing values to be treated as leaf nodes even if they have children.
