public class DomainValidator extends Object implements javax.validation.ConstraintValidator<Domain,String>
Domain name validation routines.
This validator provides methods for validating Internet domain names and top-level domains.
Domain names are evaluated according to the standards RFC1034, section 3, and RFC1123, section 2.1. No accomodation is provided for the specialized needs of other applications; if the domain name has been URL-encoded, for example, validation will fail even though the equivalent plaintext version of the same name would have passed.
Validation is also provided for top-level domains (TLDs) as defined and maintained by the Internet Assigned Numbers Authority (IANA):
isValidInfrastructureTld(java.lang.String)
- validates infrastructure TLDs
(.arpa
, etc.)isValidGenericTld(java.lang.String)
- validates generic TLDs
(.com, .org
, etc.)isValidCountryCodeTld(java.lang.String)
- validates country code TLDs
(.us, .uk, .cn
, etc.)
(NOTE: This class does not provide IP address lookup for domain names or
methods to ensure that a given domain name matches a specific IP; see
InetAddress
for that functionality.)
