tree< T, tree_node_allocator > Class Template Reference

## Data Structures
class | fixed_depth_iterator
| Iterator which traverses only the nodes at a given depth from the root. More...
class | iterator_base
| Base class for iterators, only pointers stored, no traversal logic. More...
class | iterator_base_less
| Comparator class for iterators (compares the actual node content, not pointer values). More...
class | post_order_iterator
| Depth-first iterator, first accessing the children, then the node itself. More...
class | pre_order_iterator
| Depth-first iterator, first accessing the node, then its children. More...
class | sibling_iterator
| Iterator which traverses only the nodes which are siblings of each other. More...
