Class ShortRangeFieldValidator

    java.lang.Object

          com.opensymphony.xwork2.validator.validators.FieldValidatorSupport
              com.opensymphony.xwork2.validator.validators.RangeValidatorSupport<Short>
                  com.opensymphony.xwork2.validator.validators.ShortRangeFieldValidator

All Implemented Interfaces:
  FieldValidator, ShortCircuitableValidator, Validator

    public final class ShortRangeFieldValidator

extends RangeValidatorSupport<Short>

Field Validator that checks if the short specified is within a certain range.

- fieldName - The field name this validator is validating. Required if using Plain-Validator Syntax otherwise not required
- min - the minimum value (if none is specified, it will not be checked)
- max - the maximum value (if none is specified, it will not be checked)
- parse - if set to true, minExpression and maxExpression will be evaluated to find min/max
- minExpression - expression to calculate the minimum value (if none is specified, it will not be checked)
- maxExpression - expression to calculate the maximum value (if none is specified, it will not be checked)

You can either use the min / max value or minExpression / maxExpression (when parse is set to true) - using expression can be slightly slower, see the example below. Do not use ${minExpression} and ${maxExpression} as an expression as this will turn into infinitive loop!
