public class Float2IntArrayMap extends AbstractFloat2IntMap implements Serializable, Cloneable
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.

Float2IntMapThis method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen Float2IntMap.entrySet()
so that it returns an ObjectSet
of objects of type Map.Entry (the latter makes it possible to
access keys and values with type-specific methods).

AbstractFloat2IntMapThe view is backed by the set returned by AbstractFloat2IntMap.entrySet(). Note that
no attempt is made at caching the result of this method, as this would
require adding some attributes that lightweight implementations would
not need. Subclasses may easily override this policy by calling
this method and caching the result, but implementors are encouraged to
write more efficient ad-hoc implementations.

This method performs a deep copy of this hash map; the data stored in the map, however, is not cloned. Note that this makes a difference only for object keys.
