public static class Char2ObjectFunctions.EmptyFunction<V> extends AbstractChar2ObjectFunction<V> implements Serializable, Cloneable
This class may be useful to implement your own in case you subclass a type-specific function.

defaultReturnValue()
Gets the default return value.

defaultReturnValue(V defRetValue)
Sets the default return value.

V |
get(char k)
Returns the value to which the given key is mapped.
|
V |
get(Object k)
Delegates to the corresponding type-specific method, taking care of returning
null on a missing key. |
int |
size()
Returns the intended number of keys in this function, or -1 if no such number exists.

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.
