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 derivedIntegerType
values - Note: anull
value is considered greater than any non-null
one (i.e.,null
values 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 along
one. Note: if the IntegerType value isnull
then it is consider greater than anylong
value.- Parameters:
v1
- TheIntegerType
valuev2
- Thelong
value- Returns:
- 0 if values are equal, negative if 1st value less than 2nd one,
positive otherwise. Note: the comparison uses the
longValue()
