Examples of javax.validation.Validator.validateProperty()

javax.validation.Validator.validateProperty()
Validates all constraints placed on the property of object named propertyName. @param object object to validate @param propertyName property to validate (ie field and getter constraints) @param groups group or list of groups targeted for validation(default to {@link javax.validation.groups.Default}) @return constraint violations or an empty Set if none @throws IllegalArgumentException if object is null,if propertyName null, empty or not a valid object property or if null is passed to the varargs groups @throws ValidationException if a non recoverable error happensduring the validation process
