Detailed Description¶

template<typename Node_CItr, typename Node_Itr, typename Cmp_Fn, typename _Alloc>class __gnu_pbds::tree_order_statistics_node_update< Node_CItr, Node_Itr, Cmp_Fn, _Alloc >¶

template<typename Node_CItr , typename Node_Itr , typename Cmp_Fn , typename _Alloc > tree_order_statistics_node_update< Node_CItr, Node_Itr, Cmp_Fn, _Alloc >::const_iterator __gnu_pbds::tree_order_statistics_node_update< Node_CItr, Node_Itr, Cmp_Fn, _Alloc >::find_by_order (size_typeorder) const [inline]¶

Finds an entry by __order. Returns a const_iterator to the entry with the __order order, or a const_iterator to the container object's end if order is at least the size of the container object. Definition at line 72 of file tree_policy.hpp.

template<typename Node_CItr , typename Node_Itr , typename Cmp_Fn , typename _Alloc > tree_order_statistics_node_update< Node_CItr, Node_Itr, Cmp_Fn, _Alloc >::iterator __gnu_pbds::tree_order_statistics_node_update< Node_CItr, Node_Itr, Cmp_Fn, _Alloc >::find_by_order (size_typeorder) [inline]¶

Finds an entry by __order. Returns an iterator to the entry with the __order order, or an iterator to the container object's end if order is at least the size of the container object. Definition at line 45 of file tree_policy.hpp.

template<typename Node_CItr , typename Node_Itr , typename Cmp_Fn , typename _Alloc > void __gnu_pbds::tree_order_statistics_node_update< Node_CItr, Node_Itr, Cmp_Fn, _Alloc >::operator() (node_iteratornode_it, node_const_iteratorend_nd_it) const [inline], [protected]¶

Updates the rank of a node through a node_iterator node_it; end_nd_it is the end node iterator. Definition at line 108 of file tree_policy.hpp.

template<typename Node_CItr , typename Node_Itr , typename Cmp_Fn , typename _Alloc > tree_order_statistics_node_update< Node_CItr, Node_Itr, Cmp_Fn, _Alloc >::size_type __gnu_pbds::tree_order_statistics_node_update< Node_CItr, Node_Itr, Cmp_Fn, _Alloc >::order_of_key (key_const_referencer_key) const [inline]¶

Returns the order of a key within a sequence. For exapmle, if r_key is the smallest key, this method will return 0; if r_key is a key between the smallest and next key, this method will return 1; if r_key is a key larger than the largest key, this method will return the size of r_c.
