Class EmailValidator

java.lang.Object
net.simplace.core.service.EmailValidator
public class EmailValidator extends Object

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.d- will pass validator, even though there is no TLD "d-"

.
Since:
Validator 1.1
