Public Member Functions

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.
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.
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.
