org.springframework.rules.constraint.property.ParameterizedPropertyConstraint
A constraint that returns the result of a boolean expression that tests a variable bean property value against a constant parameter value. For example: pet.age > 5 @author Keith Donald

    public PropertyConstraint not(PropertyConstraint e) {
        return new NegatedPropertyConstraint(e);
    }


    public PropertyConstraint valueProperty(String propertyName, BinaryConstraint constraint, Object value) {
        return new ParameterizedPropertyConstraint(propertyName, constraint, value);
    }
