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_type | order | ) | 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.

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.

void __gnu_pbds::tree_order_statistics_node_update< Node_CItr, Node_Itr, Cmp_Fn, _Alloc >::operator() | ( | node_iterator | node_it,
|  | node_const_iterator | end_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.

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.
