      • verifyContextNotNull

        public static void verifyContextNotNull​(Resource... contexts)
        Verifies that the supplied contexts parameter is not null, throwing an IllegalArgumentException if it is.

        The semantics of supplying null as the value of the contexts vararg is not completely clear; it can either be equivalent to supplying an empty array (i.e.: matching all statements disregarding context), or to supplying a null-Resource value (e.g.: matching all statements with no associated context). As we so far haven't been able to prefer one over the other, methods operating on contexts currently throw IllegalArgumentExceptions.

        Parameters:
        contexts - The parameter to check.
        Throws:
        IllegalArgumentException - If the supplied contexts parameter is null.
