- 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
