  org.apache.wicket.behavior.Behavior
      org.apache.wicket.validation.validator.AbstractRangeValidator<Z,Z>
          org.apache.wicket.validation.validator.RangeValidator<Z>

Type Parameters:

Z - type of validatable

All Implemented Interfaces:

Serializable, IComponentAwareEventSink, IComponentAwareHeaderContributor, IClusterable, IValidator<Z>

Direct Known Subclasses:

DateValidator

public class RangeValidator<Z extends Comparable<Z> & Serializable>
extends AbstractRangeValidator<Z,Z>

Validator for checking if a given value falls within [min,max] range. If either min or max are null they are not checked.

Resource keys:

• RangeValidator.exact if min==max
• RangeValidator.range if both min and max are not null
• RangeValidator.minimum if max is null
• RangeValidator.maximum if min is null

Error Message Variables:

• name: the id of Component that failed
• label: the label of the Component (either comes from FormComponent.labelModel or resource key <form-id>.<form-component-id>
• input: the input value
• minimum: the minimum allowed value
• maximum: the maximum allowed value
