Class SpecificationNot

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

All Implemented Interfaces:

Specification

public abstract class SpecificationNot
extends Object
implements Specification

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

Subclasses represent the logical inverse of a Specifications. An implementation should instantiate the Specifications to be satisfied in its constructor.

For example:

 public class NoSugarThanksSpec extends SpecificationNot {
     public NoSugarThanksSpec() {
         super(
             new TwoLumpsOfSugarSpec(), 
         );
     }
 }
