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)
