Annotation Interface DoubleRangeFieldValidator


@Target(METHOD) @Retention(RUNTIME) public @interface DoubleRangeFieldValidator
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.

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.
minInclusive no   Double property. The inclusive minimum the number must be.
minInclusiveExpression no   OGNL expression used to obtain the inclusive minimum the number must be.
maxInclusive no   Double property. The inclusive maximum number can be.
maxInclusiveExpression no   OGNL expression used to obtain the inclusive maximum number can be.
minExclusive no   Double property. The exclusive minimum the number must be.
minExclusiveExpression no   OGNL expression used to obtain the exclusive minimum the number must be.
maxExclusive no   Double property. The exclusive maximum number can be.
maxExclusiveExpression no   OGNL expression used to obtain 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.

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