Package org.cactoos.scalar

Class Ternary<T>

java.lang.Object

org.cactoos.scalar.ScalarEnvelope<T>

org.cactoos.scalar.Ternary<T>

Type Parameters:

T - Type of item.

All Implemented Interfaces:

Scalar<T>

public final class Ternary<T>
extends ScalarEnvelope<T>

Ternary operation.

There is no thread-safety guarantee.

This class implements Scalar, which throws a checked Exception. This may not be convenient in many cases. To make it more convenient and get rid of the checked exception you can use the Unchecked decorator. Or you may use IoChecked to wrap it in an IOException.

 new Ternary<>(
     scalar,
     value -> value > 3,
     value -> true,
     value -> false
 ).value() // will be equal to true
