public enum ConstraintTarget extends Enum<ConstraintTarget>
Enum Constant and Description |
---|
IMPLICIT
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. |
PARAMETERS
Constraint applies to the parameters of a method or a constructor
|
RETURN_VALUE
Constraint applies to the return value of a method or a constructor.
