Class ComparableSingle<T1 extends Comparable<? super T1>>

java.lang.Object

dk.cloudcreate.essentials.shared.functional.tuple.comparable.ComparableSingle<T1>

Type Parameters:

T1 - the first element type

All Implemented Interfaces:

ComparableTuple<ComparableSingle<T1>>, Serializable, Comparable<ComparableSingle<T1>>

public class ComparableSingle<T1 extends Comparable<? super T1>>
extends Object
implements ComparableTuple<ComparableSingle<T1>>

Represents a ComparableTuple with one element.
Note: ComparableSingle supports equals(Object) comparison using subclasses, e.g.:

 public class Option extends ComparableSingle<String> {
     public Option(String optionalValue) {
       super(optionalValue);
     }
 }
