bsl::unordered_multiset::load_factor

Return the current load factor of this container.

Synopsis

Declared in <bslstl_unorderedmultiset.h>

float
load_factor() const noexcept;

Description

Return the current ratio between the size of this container and the number of buckets. The load_factor is a measure of how full the container is, and a higher load factor leads to an increased number of collisions, thus resulting in a loss performance.

Return Value

ratio of size to bucket count
