class GAIResolver: (source)

Constructor: GAIResolver(reactor, getThreadPool, getaddrinfo)

Implements interfaces: twisted.internet.interfaces.IHostnameResolver

IHostnameResolver implementation that resolves hostnames by calling getaddrinfo in a thread.

Method	`__init__`	Create a `GAIResolver`.
Method	`resolveHostName`	See `IHostnameResolver.resolveHostName`
Instance Variable	`_getaddrinfo`	Undocumented
Instance Variable	`_getThreadPool`	Undocumented
Instance Variable	`_reactor`	Undocumented

def __init__(self, reactor: IReactorThreads, getThreadPool: Optional[Callable[[], ThreadPool]] = None, getaddrinfo: Callable[[str, int, int, int], _GETADDRINFO_RESULT] = getaddrinfo): (source) ¶

Create a GAIResolver.

Parameters
reactor:`IReactorThreads`	the reactor to schedule result-delivery on
getThreadPool:0-argument callable returning a `twisted.python.threadpool.ThreadPool`	a function to retrieve the thread pool to use for scheduling name resolutions. If not supplied, the use the given `reactor`'s thread pool.
getaddrinfo:callable with the same signature as `getaddrinfo`	a reference to the `getaddrinfo` to use - mainly parameterized for testing.

def resolveHostName(self, resolutionReceiver: IResolutionReceiver, hostName: str, portNumber: int = 0, addressTypes: Optional[Sequence[Type[IAddress]]] = None, transportSemantics: str = 'TCP') -> IHostResolution: (source) ¶
