Added by Rainer Hermanns, last edited by Don Brown on Nov 14, 2006 (view change)

This validator checks that a double field has a value within a specified range. If neither min nor max is set, nothing will be done.

## Usage

The annotation must be applied at method level.

## Parameters

Parameter | Required | Default | Notes
--- | --- | --- | ---
message | yes |  | field error message
key | no |  | i18n key from language specific properties file.
fieldName | no |  |
shortCircuit | no | false | If this validator should be used as shortCircuit.
type | yes | ValidatorType.FIELD | Enum value from ValidatorType. Either FIELD or SIMPLE can be used here.
minInclusive | no |  | Double property. The inclusive minimum the number must be.
maxInclusive | no |  | Double property. The inclusive maximum number can be.
minExclusive | no |  | Double property. The exclusive minimum the number must be.
maxExclusive | no |  | Double property. The exclusive maximum number can be.

If neither min nor max is set, nothing will be done.

The values for min and max must be inserted as String values so that "0" can be handled as a possible value.

## Examples

    @DoubleRangeFieldValidator(message = "Default message", key = "i18n.key", shortCircuit = true, minInclusive = "0.123", maxInclusive = "99.987")
