class twisted.internet.interfaces.IHostnameResolver(Interface): (source)
Known implementations: twisted.internet.endpoints._SimpleHostnameResolver
An 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. |
Initiate a hostname resolution.
| Parameters | resolutionReceiver | an object that will receive each resolved address as it arrives. (type: IResolutionReceiver) |
| hostName | The name of the host to resolve. If this contains non-ASCII code points, they will be converted to IDNA first. (type: str) | |
| portNumber | The port number that the returned addresses should include. (type: int) | |
| addressTypes | 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. (type: Sequence[IAddress]) | |
| transportSemantics | 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. (type: str) | |
| Returns | The resolution in progress. (type: IResolutionReceiver) | |
