std::unordered_multimap<Key,T,Hash,KeyEqual,Allocator>::reserve: std::unordered_multimap<Key,T,Hash,KeyEqual,Allocator>::reserve
Command to display std::unordered_multimap<Key,T,Hash,KeyEqual,Allocator>::reserve manual in Linux: $ man 3 std::unordered_multimap<Key,T,Hash,KeyEqual,Allocator>::reserve
NAME
std::unordered_multimap<Key,T,Hash,KeyEqual,Allocator>::reserve - std::unordered_multimap<Key,T,Hash,KeyEqual,Allocator>::reserve
Synopsis
void reserve( size_type count ); (since C++11)
Sets the number of buckets to the number needed to accomodate at least count elements without exceeding maximum load factor and rehashes the container, i.e. puts the elements into appropriate buckets considering that total number of buckets has changed. Effectively calls rehash(std::ceil(count / max_load_factor())).
Parameters
count - new capacity of the container
Return value
(none)
Complexity
Average case linear in the size of the container, worst case quadratic.
See also
reserves at least the specified number of buckets.
rehash This regenerates the hash table.
