The C++ unordered_map::~unordered_map function is used to destroy the unordered_map. The destructors of the elements are called and the used storage is deallocated.

The allocator_traits::destroy is called on each element of the unordered_map and the storage capacity of unordered_map is deallocated using its allocator.

Note:: If the elements of the unordered_map are pointers, the pointed-to objects are not destroyed.




No parameter is required.
