Class Float2DoubleFunctions.Singleton

java.lang.Object

it.unimi.dsi.fastutil.floats.AbstractFloat2DoubleFunction

it.unimi.dsi.fastutil.floats.Float2DoubleFunctions.Singleton

All Implemented Interfaces:

it.unimi.dsi.fastutil.floats.Float2DoubleFunction, java.io.Serializable, java.lang.Cloneable, java.util.function.DoubleUnaryOperator, java.util.function.Function<java.lang.Float,java.lang.Double>

Direct Known Subclasses:

Float2DoubleMaps.Singleton

Enclosing class:

Float2DoubleFunctions

public static class Float2DoubleFunctions.Singleton
extends AbstractFloat2DoubleFunction
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.
