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:

compare
Compares 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 valuev2- 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(). - See Also:

compare
Compares a IntegerType value with alongone. Note: if the IntegerType value isnullthen it is consider greater than anylongvalue.- Parameters:
v1- TheIntegerTypevaluev2- Thelongvalue- Returns:
- 0 if values are equal, negative if 1st value less than 2nd one,
positive otherwise. Note: the comparison uses the
longValue(). - See Also:
