java.lang.Object org.at4j.support.lang.SignedLong
public class SignedLong
This class represents a signed long value (i.e. a plain long
value).
If the Long
class had not been declared final
, this
class would probably have extended it.
Signed long objects are created by calling any of the static creation methods on this class.
Instances of this class are immutable.
