isValid
boolean isValid(ANNOTATION annotation,
TYPE value)
- For each value or parameter which should be checked this method will be invoked.
If the method returns true the value is valid. If it returns false the value
is considered invalid. When all constraints have been checked a ConstraintViolationException
will be thrown with all the constraint violations that were found.
- Parameters:

- the annotation to matchvalue
- the value to be checked
- Returns:
