HashMap

class HashMap[Key, Value](initialCapacity: Int, capacityMultiple: Int) extends GenericHashMap[Key, Value]

A specialized implementation of GenericHashMap with standard hashCode and equals as comparison

class GenericHashMap[Key, Value]
class MutableMap[Key, Value]
class ReadOnlyMap[Key, Value]
class Object
trait Matchable
class Any

Value members

final def hash(key: Key): Int

Hashcode is left-shifted by 1, so lowest bit is not lost when taking the index.
