Type Parameters:

A - type of the first parameter

B - type of the second parameter

All Superinterfaces:

ConstraintFunction

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 BooleanFunction2<A,B>
extends ConstraintFunction

A helper function used to define constraints which involves two parameters.

Method Summary

Modifier and Type	Method and Description
