      • toJdk8

        public GetWithoutException<I,​T> toJdk8()
        Specified by:
        toJdk8 in interface GetAndApply<I,​O,​T,​E extends java.lang.Exception>
        Returns:
        Returns a get access object without the support for generic exceptions. This was introduced to provide a workaround for JDK 8, where a bug led to incorrect exception type inference.
