Class Reference2DoubleFunctions.Singleton<K>

java.lang.Object

it.unimi.dsi.fastutil.objects.AbstractReference2DoubleFunction<K>

it.unimi.dsi.fastutil.objects.Reference2DoubleFunctions.Singleton<K>

All Implemented Interfaces:

it.unimi.dsi.fastutil.objects.Reference2DoubleFunction<K>, java.io.Serializable, java.lang.Cloneable, java.util.function.Function<K,java.lang.Double>, java.util.function.ToDoubleFunction<K>

Direct Known Subclasses:

Reference2DoubleMaps.Singleton

Enclosing class:

Reference2DoubleFunctions

public static class Reference2DoubleFunctions.Singleton<K>
extends AbstractReference2DoubleFunction<K>
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.
