Class DomainValidator

java.lang.Object

org.apache.bval.extras.constraints.net.DomainValidator

All Implemented Interfaces:

javax.validation.ConstraintValidator<Domain,CharSequence>

public class DomainValidator
extends Object
implements javax.validation.ConstraintValidator<Domain,CharSequence>

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.)
