Class Int2BooleanFunctions.Singleton

java.lang.Object

it.unimi.dsi.fastutil.ints.AbstractInt2BooleanFunction

it.unimi.dsi.fastutil.ints.Int2BooleanFunctions.Singleton

All Implemented Interfaces:

it.unimi.dsi.fastutil.ints.Int2BooleanFunction, java.io.Serializable, java.lang.Cloneable, java.util.function.Function<java.lang.Integer,java.lang.Boolean>, java.util.function.IntPredicate

Direct Known Subclasses:

Int2BooleanMaps.Singleton

Enclosing class:

Int2BooleanFunctions

public static class Int2BooleanFunctions.Singleton
extends AbstractInt2BooleanFunction
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.
