@Generated(date="2024-05-16T08:18:11+0000", value="KTypeVTypeScatterMap.java") public class CharObjectScatterMap<VType> extends CharObjectHashMap<VType>
Same as CharObjectHashMap but does not implement per-instance key mixing strategy and uses a simpler (faster) bit distribution function.

Note: read about important differences between hash and scatter sets.

    • hashKey

      protected int hashKey(char key)
      Description copied from class: CharObjectHashMap
      Returns a hash code for the given key.

      The default implementation mixes the hash of the key with CharObjectHashMap.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 CharObjectHashMap<VType>
    • from

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