- All Implemented Interfaces:
- FieldValidator, ShortCircuitableValidator, Validator
- public class StringLengthFieldValidator
- extends FieldValidatorSupport
StringLengthFieldValidator checks that a String field is of a certain length. If the "minLength"
parameter is specified, it will make sure that the String has at least that many characters. If
the "maxLength" parameter is specified, it will make sure that the String has at most that many
characters. The "trim" parameter determines whether it will trim
the
String before performing the length check. If unspecified, the String will be trimmed.
- fieldName - The field name this validator is validating. Required if using Plain-Validator Syntax otherwise not required
- maxLength - The max length of the field value. Default ignore.
- minLength - The min length of the field value. Default ignore.
- trim - Trim the field value before evaluating its min/max length. Default true
