    public @interface Nullable
    Denotes that a type (parameter, field, method return value, ...) can be null. When decorating a method call parameter, this denotes that the parameter can legitimately be null and the method will gracefully deal with it. Typically used on optional parameters. When decorating a method, this denotes the method might legitimately return null. This is a marker annotation and it has no specific attributes.
