# Class ValidatorResources

java.lang.Object
org.apache.commons.validator.ValidatorResources

All Implemented Interfaces:
  `Serializable`

public class ValidatorResources extends Object implements Serializable

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.

  - ### process

    public void process()
    Process the `ValidatorResources` object. Currently sets the `FastHashMap` s to the 'fast' mode and call the processes all other resources.
