public enum ConstraintTarget {
Discover the type when no ambiguity is present
  • if neither on a method nor a constructor, it implies the annotated element (type, field etc),
  • if on a method or constructor with no parameter, it implies RETURN_VALUE,
  • if on a method with no return value (void), it implies PARAMETERS.
Otherwise, IMPLICIT is not accepted and either RETURN_VALUE or PARAMETERS is required. This is the case for constructors with parameters and methods with parameters and return value.
