public class BoundedIntegerValidator
extends IntegerValidator
implements ConstraintDescription

Determines whether an integer field value is within minimum and maximum bounds boundaries are inclusive. The validator accepts four types of domain expression. Examples include:

• [4,10] at least 4 and at most 10
• (4,10] more than 4 and up to and including 10
• [4,10) at least 4 and below 10
• (4,10) above 4 and below 10
