From cppreference.com

 
 
 
 
~unordered_map();
(since C++11)

Destructs the container. The destructors of the elements are called and the used storage is deallocated. Note, that if the elements are pointers, the pointed-to objects are not destroyed.

[edit] Complexity

Linear in the size of the container.
