The following table provides additional information on the members of this template class.
Member Description
float load_factor() const

Returns: Average number of elements per bucket.

float max_load_factor() const

Returns: Maximum size of a bucket. If insertion of an item causes a bucket to be bigger, the implementation may repartition or increase the number of buckets.

void max_load_factor(float z)

Set maximum size for a bucket to z.

void rehash(size_type n)

Requirements: n must be a power of two.

Effects: No effect if current number of buckets is at least n. Otherwise increases number of buckets to n.
