Class RangeConstraintProcessor

java.lang.Object
  org.kuali.rice.krad.datadictionary.validation.processor.MandatoryElementConstraintProcessor<RangeConstraint>
      org.kuali.rice.krad.datadictionary.validation.processor.RangeConstraintProcessor

All Implemented Interfaces:

ConstraintProcessor<Object,RangeConstraint>

public class RangeConstraintProcessor
extends MandatoryElementConstraintProcessor<RangeConstraint>

RangeConstraintProcessor enforces range constraints - that is, constraints that keep a number or a date within a specific range

An attribute that is RangeConstrainable will expose a minimum and maximum value, and these will be validated against the passed value in the code below.
