Class Long2ObjectFunctions.Singleton<V>

java.lang.Object

it.unimi.dsi.fastutil.longs.AbstractLong2ObjectFunction<V>

it.unimi.dsi.fastutil.longs.Long2ObjectFunctions.Singleton<V>

All Implemented Interfaces:

it.unimi.dsi.fastutil.longs.Long2ObjectFunction<V>, java.io.Serializable, java.lang.Cloneable, java.util.function.Function<java.lang.Long,V>, java.util.function.LongFunction<V>

Direct Known Subclasses:

Long2ObjectMaps.Singleton

Enclosing class:

Long2ObjectFunctions

public static class Long2ObjectFunctions.Singleton<V>
extends AbstractLong2ObjectFunction<V>
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.
