IntMap

final class IntMap[Key](initialCapacity: Int, capacityMultiple: Int) extends PerfectHashing[Key]

A dense map from some Key type to Int. Dense means: All keys and values are stored in arrays from 0 up to the size of the map. Keys and values can be obtained by index usingkey(index)andvalue(index). Values can also be stored usingsetValue(index, value)`.

Value Params
capacityMultiple

The minimum multiple of capacity relative to used elements. The hash table will be re-sized once the number of elements multiplied by capacityMultiple exceeds the current size of the hash table. However, a table of size up to DenseLimit will be re-sized only once the number of elements reaches the table's size.

initialCapacity

Indicates the initial number of slots in the hash table. The actual number of slots is always a power of 2, so the initial size of the table will be the smallest power of two that is equal or greater than the given initialCapacity. Minimum value is 4.
