java.lang.Objectit.unimi.dsi.fastutil.floats.AbstractFloat2LongMap
it.unimi.dsi.fastutil.floats.Float2LongMaps.EmptyMap
An immutable class representing an empty type-specific map.
This class may be useful to implement your own in case you subclass a type-specific map.

This method must check whether the provided key is in the map using containsKey()
. Thus,
it probes the map twice. Implementors of subclasses should override it with a more efficient method.

The view is backed by the set returned by Map.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.
