Class Char2LongFunctions.Singleton

java.lang.Object

it.unimi.dsi.fastutil.chars.AbstractChar2LongFunction

it.unimi.dsi.fastutil.chars.Char2LongFunctions.Singleton

All Implemented Interfaces:

it.unimi.dsi.fastutil.chars.Char2LongFunction, java.io.Serializable, java.lang.Cloneable, java.util.function.Function<java.lang.Character,java.lang.Long>, java.util.function.IntToLongFunction

Direct Known Subclasses:

Char2LongMaps.Singleton

Enclosing class:

Char2LongFunctions

public static class Char2LongFunctions.Singleton
extends AbstractChar2LongFunction
implements java.io.Serializable, java.lang.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.
