Class AbstractBlackListValidator

java.lang.Object
  net.sf.valjax.AbstractValidator
      net.sf.valjax.AbstractBlackListValidator

All Implemented Interfaces:

InitializingBean, Validator

public abstract class AbstractBlackListValidator
extends AbstractValidator
implements InitializingBean

Provides validation for a configured black list file.

Implements afterPropertiesSet using the black list file from setBlacklistFile and loads the contents into a HashSet that is used to validate values against. Each line in the blacklist is its own entry in the HashSet.

Concrete implementations of this class need to follow the contract stated in the Validator interface. Concrete classes can also provide there own blacklist files, which will override the default blacklist file.

This is a one blackListFile per Validator setup. You can use the default blacklist file or you can supply your own, but you can not use both.
