All Implemented Interfaces:

Serializable, ServiceClass, ConstraintDescription, EditFieldValidationService, FieldValidationService

public class BoundedFloatValidator
extends FloatValidator
implements ConstraintDescription

Determines whether a float 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
