Examples of org.apache.commons.validator.ValidatorResources

org.apache.commons.validator.ValidatorResources

General purpose class for storing FormSet objects based on their associated Locale. Instances of this class are usually configured through a validation.xml file that is parsed in a constructor.

Note - Classes that extend this class must be Serializable so that instances may be used in distributable application server environments.

The use of FastHashMap is deprecated and will be replaced in a future release.
