Class Object2ByteFunctions.Singleton<K>

java.lang.Object

it.unimi.dsi.fastutil.objects.AbstractObject2ByteFunction<K>

it.unimi.dsi.fastutil.objects.Object2ByteFunctions.Singleton<K>

All Implemented Interfaces:

Object2ByteFunction<K>, Serializable, Cloneable, Function<K,Byte>, ToIntFunction<K>

Direct Known Subclasses:

Object2ByteMaps.Singleton

Enclosing class:

Object2ByteFunctions

public static class Object2ByteFunctions.Singleton<K>
extends AbstractObject2ByteFunction<K>
implements Serializable, Cloneable

An immutable class representing a type-specific singleton function. Note that the default return value is still settable.

Note that albeit the function is immutable, its default return value may be changed.

This class may be useful to implement your own in case you subclass a type-specific function.
