net.ashwork.functionality.arity.operator

Interface TernaryOperator<T>

Type Parameters:

T - The type of the operands and result of the operator

All Superinterfaces:

TriFunction<T,T,T,T>

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 TernaryOperator<T>
extends TriFunction<T,T,T,T>

Represents an operation upon three operands of the same type, producing a result of the same type as the operands. This is a specialization of TriFunction for the case where the operands and the result are all of the same type.

This is a functional interface whose functional method is TriFunction.apply(Object, Object, Object).

conditional

static <T> TernaryOperator<T> conditional(java.util.function.Predicate<? super T> predicate)

Type Parameters:

T - The type of the input argument of the predicate

Parameters:

predicate - A Predicate for testing a specific value

Returns:

An operator which returns either the second or third argument based on the predicate.

Throws:

java.lang.NullPointerException - If the predicate is null
