@Generated(date="2024-02-21T10:44:44+0000", value="KTypeVTypeIdentityHashMap.java") public class ObjectIntIdentityHashMap<KType> extends ObjectIntHashMap<KType>
An identity hash map of Object to int.
  • Constructor Details

    • ObjectIntIdentityHashMap

      public ObjectIntIdentityHashMap()
      New instance with sane defaults.
    • ObjectIntIdentityHashMap

      public ObjectIntIdentityHashMap(int expectedElements)
      New instance with sane defaults.
      Parameters:
      expectedElements - The expected number of elements guaranteed not to cause buffer expansion (inclusive).
    • ObjectIntIdentityHashMap

      public ObjectIntIdentityHashMap(int expectedElements, double loadFactor)
      New instance with sane defaults.
      Parameters:
      expectedElements - The expected number of elements guaranteed not to cause buffer expansion (inclusive).
      loadFactor - The load factor for internal buffers. Insane load factors (zero, full capacity) are rejected by ObjectIntHashMap.verifyLoadFactor(double).
    • ObjectIntIdentityHashMap

      public ObjectIntIdentityHashMap(int expectedElements, double loadFactor, HashOrderMixingStrategy orderMixer)
      New instance with the provided defaults.
      Parameters:
      expectedElements - The expected number of elements guaranteed not to cause a rehash (inclusive).
      loadFactor - The load factor for internal buffers. Insane load factors (zero, full capacity) are rejected by ObjectIntHashMap.verifyLoadFactor(double).
      orderMixer - Hash key order mixing strategy. See HashOrderMixing for predefined implementations. Use constant mixers only if you understand the potential consequences.
    • ObjectIntIdentityHashMap

      public ObjectIntIdentityHashMap(ObjectIntAssociativeContainer<? extends KType> container)
      Create a hash map from all key-value pairs of another container.
  • Method Details

    • hashKey

      public int hashKey(KType key)
      Description copied from class: ObjectIntHashMap
      Returns a hash code for the given key.

      The default implementation mixes the hash of the key with ObjectIntHashMap.keyMixer to differentiate hash order of keys between hash containers. Helps alleviate problems resulting from linear conflict resolution in open addressing.

      The output from this function should evenly distribute keys across the entire integer range.

      Overrides:
      hashKey in class ObjectIntHashMap<KType>
    • equals

      public boolean equals(Object v1, Object v2)
      Overrides:
      equals in class ObjectIntHashMap<KType>
    • from

      public static <KType> ObjectIntIdentityHashMap<KType> from(KType[] keys, int[] values)
      Creates a hash map from two index-aligned arrays of key-value pairs.
