## Annotation Type IntRangeFieldValidator

-     @Target(value=METHOD)
       @Retention(value=RUNTIME)
      public @interface IntRangeFieldValidator

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

  Annotation usage:

  The annotation must be applied at method level.

  Annotation parameters:

  Parameter | Required | Default | Notes
  --- | --- | --- | ---
  message | yes |  | field error message
  key | no |  | i18n key from language specific properties file.
  messageParams | no |  | Additional params to be used to customize message - will be evaluated against the Value Stack
  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.
  min | no |  | Integer property. The minimum the number must be.
  minExpression | no |  | OGNL expression used to obtain the minimum the number must be.
  max | no |  | Integer property. The maximum number can be. Can be an expression.!
  maxExpression | no |  | OGNL expression used to obtain the maximum number can be.
  parse | no | false | Enable parsing of min/max value.

  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.

  Example code:

       @IntRangeFieldValidator(message = "Default message", key = "i18n.key", shortCircuit = true, min = "0", max = "42")

       @IntRangeFieldValidator(message = "Default message", key = "i18n.key", shortCircuit = true, minExpression = "${minValue}", maxExpression = "${maxValue}")

        ""

  - - #### key

          public abstract String key

      Returns:
        The message key to lookup for i18n.
      Default:
        ""
