std::{{{1}}}::rehash

من cppreference.com
void rehash( size_type count );
(since C++11)

Sets the number of buckets to ‎count‎ and rehashes the container, i.e. puts the elements into appropriate buckets considering that total number of buckets has changed. If the new number of buckets makes load factor more than maximum load factor (count < size() / max_load_factor()), then the new number of buckets is at least size() / max_load_factor().

[تعديل] Parameters

count - new number of buckets

[تعديل] Return value

(none)

[تعديل] Complexity

Average case linear in the size of the container, worst case quadratic.

[تعديل] Notes

‎rehash(0)‎ may be used to force an unconditional rehash, such as after suspension of automatic rehashing by temporary increasing max_load_factor().
