java.lang.Objectit.unimi.dsi.fastutil.floats.AbstractFloat2ShortFunction
it.unimi.dsi.fastutil.floats.Float2ShortFunctions.EmptyFunction
public static class Float2ShortFunctions.EmptyFunction
An immutable class representing an empty type-specific function.
This class may be useful to implement your own in case you subclass a type-specific function.

to
denote that the map does not contain the specified key. It must be
0/false
/null
by default.

AbstractFloat2ShortFunction
null
on a missing key.
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.

if no value was present for the given key.Map.get(Object)
public int size()
Function
Most function implementations will have some knowledge of the intended number of keys in their domain. In some cases, however, this might not be possible.
