Public Member Functions¶
iterator find_by_order (size_type)
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. const_iterator find_by_order
(size_type) const
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. size_type order_of_key
(key_const_reference) const
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.
Protected Member Functions¶
void operator() (node_iterator, node_const_iterator) const
Updates the rank of a node through a node_iterator node_it; end_nd_it is the
end node iterator.
