IBucketSet.this

Constructor.

class IBucketSet

protected

this

(

size_t n

float load_factor = 0.75

)

Parameters

bucket_element_allocator IAllocator: bucket element allocator
n size_t: expected number of elements in mapping
load_factor float: ratio of n to the number of internal buckets. The desired (approximate) number of elements per bucket. For example, 0.5 sets the number of buckets to double n; for 2 the number of buckets is the half of n. load_factor must be greater than 0. The load factor is basically a trade-off between memory usage (number of buckets) and search time (number of elements per bucket).
