    • disallowed

      Class<?>[] disallowed
      Disallowed classes for recursive components. All derived classes from the disallowed list will be disallowed too. Each disallowed class must be assignable to the annotated parameter type, or to its element type when the parameter is a List or an array.
      Returns:
      disallowed classes
      Default:
      {}

    • min

      int min
      Minimum number of elements when this annotation is used on a list or array. Ignored for scalar component parameters.
      Returns:
      minimum collection size, inclusive
      Default:
      0

    • max

      int max
      Maximum number of elements when this annotation is used on a list or array. Ignored for scalar component parameters.
      Returns:
      maximum collection size, inclusive
      Default:
      3
