Detailed Description

template<typename _Key, typename _Data, typename _Value = std::pair<_Key, _Data>, typename _Compare = std::less<_Key>, typename _Traits = btree_default_map_traits<_Key, _Data>, bool _Duplicates = false, typename _Alloc = std::allocator<_Value>, bool _UsedAsSet = false>
struct stx::btree< _Key, _Data, _Value, _Compare, _Traits, _Duplicates, _Alloc, _UsedAsSet >::node

The header structure of each node in-memory.

This structure is extended by inner_node or leaf_node.
