public class Float2CharArrayMap extends AbstractFloat2CharMap 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.

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

Float2CharMapThis method is necessary because there is no inheritance along type parameters: it is thus impossible to strengthen Float2CharMap.entrySet() so that it returns an
ObjectSet of type-specific entries (the latter makes it possible to access keys and values with type-specific methods).

AbstractFloat2CharMapThe view is backed by the set returned by AbstractFloat2CharMap.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.
