Annotation Interface Opt

@Documented
@Retention(CLASS)
@Target({FIELD,METHOD,PARAMETER,LOCAL_VARIABLE,TYPE_USE,TYPE_PARAMETER})
public @interface Opt

Indicates that the value null may appear. This is the opposite to the "NonNull" option, as proposed by oracle, but strictness is the normal case in our way of coding. It can be applied to the following places where types do occur:

  class c {
     public static @Opt Integer i ; 
     public @Opt String makeString (final String s; final @Opt String i) {..}
  }
