public abstract class PrimitiveTotalPredicate

extends TotalPredicate

A class of total predicates that have no subpredicates.

This class implements the nbSubPredicates() and getSubPredicates() methods for predicates that don't contain any sub predicates.

Typically, this class will be used as an anonymous inner class as follows:

TotalPredicate myPredicate = new PrimitiveTotalPredicate() {
            public boolean eval(Object o) {
              //calculate boolean value
              //using the given object
            }
          };
