Abstract parent class for suppliers of input data points for theories. Extend this class to customize how
Theories
runner
finds accepted data points. Then use your class together with @ParametersSuppliedBy on input
parameters for theories.
For example, here is a supplier for values between two integers, and an annotation that references it:
@Retention(RetentionPolicy.RUNTIME) @ParametersSuppliedBy(BetweenSupplier.class) public @interface Between { int first(); int last(); } public static class BetweenSupplier extends ParameterSupplier { @Override public List<PotentialAssignment> getValueSources(ParameterSignature sig) { List<PotentialAssignment> list = new ArrayList<PotentialAssignment>(); Between annotation = (Between) sig.getSupplierAnnotation(); for (int i = annotation.first(); i <= annotation.last(); i++) list.add(PotentialAssignment.forValue("ints", i)); return list; } }
