      • create

        public static <T> Conversions.WrappedArray<T> create​(T[] array)
        Creates a new Conversions.WrappedArray that is backed by the given array.
        Type Parameters:
        T - the element type of the created list.
        Parameters:
        array - the to-be-wrapped array. May be null which will cause any method on the result object to fail with a NullPointerException.
        Returns:
