cvs commit: jakarta-commons/validator/src/share/org/apache/commons/validator CreditCardValidator.java GenericValidator.java
dgraham 2003/06/07 12:13:21
Modified: validator/src/share/org/apache/commons/validator
CreditCardValidator.java GenericValidator.java
Log:
Added validation options to CreditCardValidator to allow only
certain card types to pass validation. This required
CreditCardValidator to not be a Singleton.
Currently the options are passed into the constructor (like UrlValidator) but we may
need to consider passing the options into the isValid() method
so that one CreditCardValidator instance can be used to
validate with different options.
This still needs a unit test.
