t.i.b.ThreadedResolver(object) : class documentation

Part of twisted.internet.base View Source View In Hierarchy

Known subclasses: twisted.names.client.ThreadedResolver

Implements interfaces: twisted.internet.interfaces.IResolverSimple

ThreadedResolver uses a reactor, a threadpool, and socket.gethostbyname to perform name lookups without blocking the reactor thread. It also supports timeouts indepedently from whatever timeout logic socket.gethostbyname might have.

Instance Variables reactor The reactor the threadpool of which will be used to call socket.gethostbyname and the I/O thread of which the result will be delivered.

Method	__init__	Undocumented
Method	getHostByName	See `twisted.internet.interfaces.IResolverSimple.getHostByName`.
Method	_fail	Undocumented
Method	_cleanup	Undocumented
Method	_checkTimeout	Undocumented

Undocumented

from twisted.internet.interfaces.IResolverSimple

See twisted.internet.interfaces.IResolverSimple.getHostByName.

Note that the elements of timeout are summed and the result is used as a timeout for the lookup. Any intermediate timeout or retry logic is left up to the platform via socket.gethostbyname.
