- All Implemented Interfaces:
- FieldValidator, ShortCircuitableValidator, Validator
public final class IntRangeFieldValidator
- extends RangeValidatorSupport<Integer>
Field Validator that checks if the integer 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!
