java.lang.Objectorg.apache.commons.validator.routines.EmailValidator
public class EmailValidator
Perform email validations.
This class is a Singleton; you can retrieve the instance via the getInstance() method.
Based on a script by Sandeep V. Tamhankar http://javascript.internet.com
This implementation is not guaranteed to catch all possible errors in an email address. For example, an address like nobody@noplace.somedog will pass validator, even though there is no TLD "somedog"
.
