Class Float2ReferenceArrayMap<V>

All Implemented Interfaces:
Float2ReferenceFunction<V>, Float2ReferenceMap<V>, Function<Float,V>, Serializable, Cloneable, DoubleFunction<V>, Function<Float,V>, Map<Float,V>

public class Float2ReferenceArrayMap<V> extends AbstractFloat2ReferenceMap<V> 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.

    • Float2ReferenceArrayMap

      public Float2ReferenceArrayMap(float[] key, Object[] 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).
    • Float2ReferenceArrayMap

      public Float2ReferenceArrayMap()
      Creates a new empty array map.
    • Float2ReferenceArrayMap

      public Float2ReferenceArrayMap(int capacity)
      Creates a new empty array map of given capacity.
      Parameters:
      capacity - the initial capacity.
    • Float2ReferenceArrayMap

      public Float2ReferenceArrayMap(Float2ReferenceMap<V> m)
      Creates a new empty array map copying the entries of a given map.
      Parameters:
      m - a map.
    • Float2ReferenceArrayMap

      public Float2ReferenceArrayMap(Map<? extends Float,? extends V> m)
      Creates a new empty array map copying the entries of a given map.
      Parameters:
      m - a map.
    • Float2ReferenceArrayMap

      public Float2ReferenceArrayMap(float[] key, Object[] 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.
