Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface NonNullProperty<T>
extends Property<T>

A property whose value is never null.

Method Summary

Modifier and Type	Method	Description
default boolean	isNotNull()	Returns true, because the value of this property is never null.
default FixedBooleanProperty	isNotNullProperty()	Returns a boolean property whose value is always true.
default NonNullProperty<T>	replaceNull(T defaultValue)	Returns this property, whose value is never null.
