Class IntRangeFieldValidator

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!
