Class Short2ShortArrayMap

All Implemented Interfaces:
Function<Short,Short>, Short2ShortFunction, Short2ShortMap, Serializable, Cloneable, Function<Short,Short>, IntUnaryOperator, Map<Short,Short>

public class Short2ShortArrayMap extends AbstractShort2ShortMap 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.

    • Short2ShortArrayMap

      public Short2ShortArrayMap(short[] 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).
    • Short2ShortArrayMap

      public Short2ShortArrayMap()
      Creates a new empty array map.
    • Short2ShortArrayMap

      public Short2ShortArrayMap(int capacity)
      Creates a new empty array map of given capacity.
      Parameters:
      capacity - the initial capacity.
    • Short2ShortArrayMap

      public Short2ShortArrayMap(Short2ShortMap m)
      Creates a new empty array map copying the entries of a given map.
      Parameters:
      m - a map.
    • Short2ShortArrayMap

      public Short2ShortArrayMap(Map<? extends Short,? extends Short> m)
      Creates a new empty array map copying the entries of a given map.
      Parameters:
      m - a map.
    • Short2ShortArrayMap

      public Short2ShortArrayMap(short[] 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.
