OverviewPackageAttributesInitializerMethods

Performance-related settings for a hashtable based collection like HashMap or HashSet.

The size of the backing Array is called the capacity of the hashtable.

  • The capacity of a new instance is specified by the given initialCapacity.
  • The capacity is increased, and the elements rehashed, when the ratio of collection size to capacity exceeds the given loadFactor.
  • The new capacity is the product of the current capacity and the given growthFactor.

Initializer
Hashtable(Integer initialCapacity = ..., Float loadFactor = ..., Float growthFactor = ...)
Parameters:
  • initialCapacity = 16

    The initial capacity of the backing array.

  • loadFactor = 0.75

    The ratio between the number of elements and the capacity which triggers a rebuild of the hash set.

  • growthFactor = 2.0

    The factor used to determine the new size of the backing array when a new backing array is allocated.
