Examples of org.apache.commons.validator.ValidatorAction

org.apache.commons.validator.ValidatorAction
Contains the information to dynamically create and run a validation method. This is the class representation of a pluggable validator that can be defined in an xml file with the <validator> element. Note: The validation method is assumed to be thread safe. @version $Revision: 478334 $ $Date: 2006-11-22 21:31:54 +0000 (Wed, 22 Nov 2006) $
