const_local_iterator end( size_type n ) const;		(since C++11)
const_local_iterator cend( size_type n ) const;		(since C++11)

Returns an iterator to the element following the last element of the bucket with index n. . This element acts as a placeholder, attempting to access it results in undefined behavior.

Parameters

n

-

the index of the bucket to access

Return value

iterator to the element following the last element

Complexity

Constant
