public class IntegerValue
extends NumberValue

Implementation of BaseType integer value.

An integer value is A whole number in the range [-2147483648, 2147483647].

Example values: 1, +3, -4.

This class is not mutable and cannot contain NULL value.

Cardinality of this class is always single and BaseType is always integer.
