public class Char2ShortArrayMap extends AbstractChar2ShortMap implements Serializable, Cloneable
A simple, brute-force implementation of a map based on two parallel backing arrays.

The main purpose of this implementation is that of wrapping cleanly the brute-force approach to the storage of a very small number of pairs: just put them into two parallel arrays and scan linearly to find an item.

    • Char2ShortArrayMap

      public Char2ShortArrayMap(char[] key, short[] value)
      Creates a new empty array map with given key and value backing arrays. The resulting map will have as many entries as the given arrays.

      It is responsibility of the caller that the elements of key are distinct.

      Parameters:
      key - the key array.
      value - the value array (it must have the same length as key).

    • Char2ShortArrayMap

      public Char2ShortArrayMap()
      Creates a new empty array map.

    • Char2ShortArrayMap

      public Char2ShortArrayMap(int capacity)
      Creates a new empty array map of given capacity.
      Parameters:
      capacity - the initial capacity.

    • Char2ShortArrayMap

      public Char2ShortArrayMap(Char2ShortMap m)
      Creates a new empty array map copying the entries of a given map.
      Parameters:
      m - a map.

    • Char2ShortArrayMap

      public Char2ShortArrayMap(Map<? extends Character,? extends Short> m)
      Creates a new empty array map copying the entries of a given map.
      Parameters:
      m - a map.

    • Char2ShortArrayMap

      public Char2ShortArrayMap(char[] key, short[] value, int size)
      Creates a new array map with given key and value backing arrays, using the given number of elements.

      It is responsibility of the caller that the first size elements of key are distinct.

      Parameters:
      key - the key array.
      value - the value array (it must have the same length as key).
      size - the number of valid elements in key and value.
