class IHostnameResolver(Interface): (source)
Known implementations: twisted.internet._resolver.GAIResolver, twisted.internet._resolver.SimpleResolverComplexifier, twisted.internet.endpoints._SimpleHostnameResolver
IHostnameResolver can resolve a host name and port number into a series of IAddress objects.| Present Since | |
| Twisted 17.1.0 |
| Method | resolveHostName |
Initiate a hostname resolution. |
| Parameters | |
resolutionReceiver:IResolutionReceiver | an object that will receive each resolved address as it arrives. |
hostName:str | The name of the host to resolve. If this contains non-ASCII code points, they will be converted to IDNA first. |
portNumber:int | The port number that the returned addresses should include. |
addressTypes:Sequence[ | An iterable of implementors of IAddress that are acceptable values for resolutionReceiver to receive to its addressResolved. In practice, this means an iterable containing twisted.internet.address.IPv4Address, twisted.internet.address.IPv6Address, both, or neither. |
transportSemantics:str | A string describing the semantics of the transport; either 'TCP' for stream-oriented transports or 'UDP' for datagram-oriented; see twisted.internet.address.IPv6Address.type and twisted.internet.address.IPv4Address.type. |
| Returns | |
IResolutionReceiver | The resolution in progress. |
