Package org.apache.commons.validator

Class Arg

java.lang.Object
org.apache.commons.validator.Arg
All Implemented Interfaces:
Serializable, Cloneable
public class Arg extends Object implements Cloneable, Serializable

A default argument or an argument for a specific validator definition (ex: required) can be stored to pass into a message as parameters. This can be used in a pluggable validator for constructing locale sensitive messages by using java.text.MessageFormat or an equivalent class. The resource field can be used to determine if the value stored in the argument is a value to be retrieved from a locale sensitive message retrieval system like java.util.PropertyResourceBundle. The resource field defaults to 'true'.

Instances of this class are configured with an <arg> xml element.
