Class SpecificationOr

java.lang.Object
  org.nakedobjects.applib.spec.SpecificationOr

All Implemented Interfaces:

Specification

public abstract class SpecificationOr
extends java.lang.Object
implements Specification

Adapter to make it easy to perform boolean algebra on Specifications.

Subclasses represent the conjunction of multiple Specifications. An implementation should instantiate the Specifications to be satisfied in its constructor.

For example:

 public class TeaOrCoffeeSpec extends SpecificationOr {
     public TeaOrCoffeeSpec() {
         super(
             new MustBeTeaSpec(), 
             new MustBeCoffeeSpec()
         );
     }
 }
