Member Function Documentation

find_by_order() [1/2]

template<typename Node_CItr , typename Node_Itr , typename Cmp_Fn , typename _Alloc >

iterator __gnu_pbds::tree_order_statistics_node_update< Node_CItr, Node_Itr, Cmp_Fn, _Alloc >::find_by_order ( size_type  )

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.

find_by_order() [2/2]

template<typename Node_CItr , typename Node_Itr , typename Cmp_Fn , typename _Alloc >

const_iterator __gnu_pbds::tree_order_statistics_node_update< Node_CItr, Node_Itr, Cmp_Fn, _Alloc >::find_by_order ( size_type  ) 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.

operator()()

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_iterator  , node_const_iterator    ) const

inlineprotected

Updates the rank of a node through a node_iterator node_it; end_nd_it is the end node iterator.

order_of_key()

template<typename Node_CItr , typename Node_Itr , typename Cmp_Fn , typename _Alloc >

size_type __gnu_pbds::tree_order_statistics_node_update< Node_CItr, Node_Itr, Cmp_Fn, _Alloc >::order_of_key ( key_const_reference  ) 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.
