init(self, settings=None)
(Constructor)

x.__init__(...) initializes x; see help(type(x)) for signature

Overrides: object.__init__: (inherited documentation)

resolve_srv(self, domain, service, protocol, callback)

Start looking up an SRV record for service at domain.

callback will be called with a properly sorted list of (hostname, port) pairs on success. The list will be empty on error and it will contain only (".", 0) when the service is explicitely disabled.

Parameters:

domain - domain name to look up
service - service name e.g. 'xmpp-client'
protocol - protocol name, e.g. 'tcp'
callback - a function to be called with a list of received addresses

Overrides: interfaces.Resolver.resolve_srv

(inherited documentation)

resolve_address(self, hostname, callback, allow_cname=True)

Start looking up an A or AAAA record.

callback will be called with a list of (family, address) tuples on success. Family is socket.AF_INET or socket.AF_INET6, the address is IPv4 or IPv6 literal. The list will be empty on error.

Parameters:

hostname (unicode) - the host name to look up
callback (function accepting a single argument) - a function to be called with a list of received addresses
allow_cname (bool) - True if CNAMEs should be followed

Overrides: interfaces.Resolver.resolve_address
