public interface FSBooleanConstraint extends FSConstraint
Interface for a boolean constraint. A boolean constraint contains a single condition, either true or false. To set the condition, use

To use the constraint, invoke its match(boolean) method, passing the value to test. You can also embed this test with a path specification, using the ConstraintFactory.embedConstraint(FeaturePath, FSConstraint) method, and use it to test feature structures, or combine it with other tests using the ConstraintFactory.and(FSMatchConstraint, FSMatchConstraint) and ConstraintFactory.or(FSMatchConstraint, FSMatchConstraint) methods.
