Class LowestOf<T extends Comparable<? super T>>

  • Type Parameters:
    T - Scalar type
    All Implemented Interfaces:
    Scalar<T>
    public final class LowestOf<T extends Comparable<? super T>>
extends ScalarEnvelope<T>
    Find the lowest item.

    Here is how you can use it to find lowest of Comparable items:

     final String lowest = new LowestOf<String>(
         () -> "Banana", () -> "Apple", () -> "Orange"
     ).value();
 // -> lowest == "Apple"

 final Character lowestChar = new LowestOf<>('B', 'U', 'G').value();
 // -> lowestChar == 'B'

    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.

    There is no thread-safety guarantee.
