Represents a native integer value, which may have a platform-specific size
 (e.g. 
long on unix-based platforms).
 May optionally indicate an unsigned attribute, such that when a value is
 extracted into a larger-sized container (e.g. int retrieved
 via Number.longValue(), the value will be unsigned.  Default behavior
 is signed.- Author:

compareCompares 2 derivedIntegerTypevalues - Note: anullvalue is considered greater than any non-nullone (i.e.,nullvalues are "pushed" to the end of a sorted array / list of values)- Type Parameters:
- T- the derived integer type
- Parameters:
- v1- The 1st value
- v2- The 2nd value
- Returns:
- 0 if values are equal - including if both are null, negative if 1st value less than 2nd one, positive otherwise. Note: the comparison uses thelongValue().

compareCompares a IntegerType value with alongone. Note: if the IntegerType value isnullthen it is consider greater than anylongvalue.- Parameters:
- v1- The- IntegerTypevalue
- v2- The- longvalue
- Returns:
- 0 if values are equal, negative if 1st value less than 2nd one,
 positive otherwise. Note: the comparison uses the longValue().
