Detailed Description

Wraps a resolver with a mapping of overrides.

This can be used to make local DNS changes (e.g. for testing)
without modifying system-wide settings.

The mapping can contain either host strings or host-port pairs.

.. versionadded:: 3.1

Reimplemented from tornado.netutil.Resolver.

def tornado.netutil.OverrideResolver.initialize	(		self,
			resolver,
			mapping
	)

Definition at line 389 of file netutil.py.

def tornado.netutil.OverrideResolver.resolve	(		self,
			host,
			port,
			family,
			callback
	)

Resolves an address.

The ``host`` argument is a string which may be a hostname or a
literal IP address.

Returns a `.Future` whose result is a list of (family,
address) pairs, where address is a tuple suitable to pass to
`socket.connect <socket.socket.connect>` (i.e. a ``(host,
port)`` pair for IPv4; additional fields may be present for
IPv6). If a ``callback`` is passed, it will be run with the
result as an argument when it is complete.
