@Generated(date="2024-05-16T08:18:11+0000", value="KTypeVTypeIdentityHashMap.java") public class ObjectCharIdentityHashMap<KType> extends ObjectCharHashMap<KType>
An identity hash map of Object to char.
  • Constructor Details

    • ObjectCharIdentityHashMap

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

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

      public ObjectCharIdentityHashMap(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 ObjectCharHashMap.verifyLoadFactor(double).
    • ObjectCharIdentityHashMap

      public ObjectCharIdentityHashMap(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 ObjectCharHashMap.verifyLoadFactor(double).
      orderMixer - Hash key order mixing strategy. See HashOrderMixing for predefined implementations. Use constant mixers only if you understand the potential consequences.
    • ObjectCharIdentityHashMap

      public ObjectCharIdentityHashMap(ObjectCharAssociativeContainer<? 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: ObjectCharHashMap
      Returns a hash code for the given key.

      The default implementation mixes the hash of the key with ObjectCharHashMap.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 ObjectCharHashMap<KType>
    • equals

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

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