public class LazyLong
LazyObject for storing a value of Long.
Part of the code is adapted from Apache Harmony Project. As with the specification, this implementation relied on code laid out in Henry S. Warren, Jr.'s Hacker's Delight, (Addison Wesley, 2002) as well as The Aggregate's Magic Algorithms.
