public class BoundedDoubleValidator
extends DoubleValidator
implements ConstraintDescription

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

• [4.5,10.1] at least 4.5 and at most 10.1
• (4.5,10.1] more than 4.5 and up to and including 10.1
• [4.5,10.1) at least 4.5 and below 10.1
• (4.5,10.1) above 4.5 and below 10.1
