java.lang.Object

it.unimi.dsi.fastutil.objects.AbstractObject2BooleanFunction<K>

it.unimi.dsi.fastutil.objects.Object2BooleanFunctions.Singleton<K>

All Implemented Interfaces:

Object2BooleanFunction<K>, java.io.Serializable, java.lang.Cloneable, java.util.function.Function<K,java.lang.Boolean>, java.util.function.Predicate<K>

Direct Known Subclasses:

Object2BooleanMaps.Singleton

Enclosing class:

Object2BooleanFunctions

public static class Object2BooleanFunctions.Singleton<K>
extends AbstractObject2BooleanFunction<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.
