Class UnsignedConversions

  • public class UnsignedConversions
extends Object
    Conversion utilities between unsigned primitives and standard Java primitives.

    Since we need all the combinations and since the standard libraries provide only some, we chose to re-implement all the cases here for readability and convenience. Note that the only conversions that are different are the widening from unsigned to signed. All other conversions are the same.
