Annotation Type NonnullElements


  • @Documented
    @Target({FIELD,LOCAL_VARIABLE,METHOD,PARAMETER})
    public @interface NonnullElements
    Indicates that the annotated collection cannot contain any null elements:
    • Input collections as parameters MUST NOT contain any null elements.
    • Collections returned by methods WILL NOT contain any null elements, and if mutable, callers MUST NOT add a null element.

    Behavior is undefined if these constraints are violated. Some form of exception should be expected.
