Package org.apache.commons.validator

Class EmailValidator

  • public class EmailValidator
extends java.lang.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 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"

    Validator 1.1
