Description
Field Validator that checks if the double specified is within a certain range.
Parameters
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.
Warning: do not use
${minInclusiveExpression},${maxInclusiveExpression},${minExclusiveExpressionExpression}and${maxExclusive}as an expression as this will turn into infinitive loop!
