java.lang.Objectorg.apache.bval.extras.constraints.net.DomainValidator
public class DomainValidator
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.)

public boolean isValid(String domain, ConstraintValidatorContext context)
isValid
in interface ConstraintValidator<Domain,String>
boolean isValidTld(String tld)
String
matches any
IANA-defined top-level domain. Leading dots are ignored if present.
The search is case-sensitive.
tld
- the parameter to check for TLD status
static boolean isValidInfrastructureTld(String iTld)
String
matches any
IANA-defined infrastructure top-level domain. Leading dots are
ignored if present. The search is case-sensitive.
iTld
- the parameter to check for infrastructure TLD status
static boolean isValidGenericTld(String gTld)
String
matches any
IANA-defined generic top-level domain. Leading dots are ignored
if present. The search is case-sensitive.
gTld
- the parameter to check for generic TLD status
static boolean isValidCountryCodeTld(String ccTld)
String
matches any
IANA-defined country code top-level domain. Leading dots are
ignored if present. The search is case-sensitive.
ccTld
- the parameter to check for country code TLD status
static boolean isValidLocalTld(String iTld)
String
matches any
widely used "local" domains (localhost or localdomain). Leading dots are
ignored if present. The search is case-sensitive.
iTld
- the parameter to check for local TLD status
