Class Double2FloatFunctions.Singleton

java.lang.Object

it.unimi.dsi.fastutil.doubles.AbstractDouble2FloatFunction

it.unimi.dsi.fastutil.doubles.Double2FloatFunctions.Singleton

All Implemented Interfaces:

it.unimi.dsi.fastutil.doubles.Double2FloatFunction, java.io.Serializable, java.lang.Cloneable, java.util.function.DoubleUnaryOperator, java.util.function.Function<java.lang.Double,java.lang.Float>

Direct Known Subclasses:

Double2FloatMaps.Singleton

Enclosing class:

Double2FloatFunctions

public static class Double2FloatFunctions.Singleton
extends AbstractDouble2FloatFunction
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.
