Class EmailValidator

java.lang.Object
org.apache.commons.validator.EmailValidator
@Deprecated public class EmailValidator extends Object
Deprecated.
Use the new EmailValidator in the routines package. This class will be removed in a future release.

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 https://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"

.

1.1
