- All Implemented Interfaces:
- FieldValidator, ShortCircuitableValidator, Validator
public class DoubleRangeFieldValidator
- extends FieldValidatorSupport
Field Validator that checks if the double specified is within a certain range.
- fieldName - The field name this validator is validating. Required if using Plain-Validator Syntax otherwise not required
- minInclusive - the minimum inclusive value in FloatValue format specified by Java language (if none is specified, it will not be checked)
- maxInclusive - the maximum inclusive value in FloatValue format specified by Java language (if none is specified, it will not be checked)
- minExclusive - the minimum exclusive value in FloatValue format specified by Java language (if none is specified, it will not be checked)
- maxExclusive - the maximum exclusive value in FloatValue format specified by Java language (if none is specified, it will not be checked)
- minInclusiveExpression - the minimum inclusive value specified as a OGNL expression (if none is specified, it will not be checked)
- maxInclusiveExpression - the maximum inclusive value specified as a OGNL expression (if none is specified, it will not be checked)
- minExclusiveExpression - the minimum exclusive value specified as a OGNL expression (if none is specified, it will not be checked)
- maxExclusiveExpression - the maximum exclusive value specified as a OGNL expression (if none is specified, it will not be checked)
You can specify either minInclusive, maxInclusive, minExclusive and maxExclusive or minInclusiveExpression, maxInclusiveExpression,
minExclusiveExpression and maxExclusiveExpression as a OGNL expression, see example below. You can always try to mix params
but be aware that such behaviour was not tested.
Do not use ${minInclusiveExpression}, ${maxInclusiveExpression}, ${minExclusiveExpressionExpression} and ${maxExclusive}
as an expression as this will turn into infinitive loop!
