Annotation Interface UniqueElements

@Target({ANNOTATION_TYPE,PARAMETER,TYPE_USE}) @Retention(RUNTIME) @Documented @API(status=MAINTAINED, since="1.4.0") public @interface UniqueElements
Add a uniqueness constraint to a Collection, Stream or Array parameter. Applies to List, Set, Stream, and arrays which are also annotated with @ForAll.

Unlike the old and meanwhile removed annotation Unique this annotation is added to the collection/array/stream parameter and NOT to the element type.
