t.n.c.ResolverBase : class documentation

Part of twisted.names.common View Source View In Hierarchy

Known subclasses: twisted.names.authority.FileAuthority, twisted.names.cache.CacheResolver, twisted.names.client.Resolver, twisted.names.hosts.Resolver, twisted.names.resolve.ResolverChain, twisted.names.root.Resolver, twisted.names.secondary.SecondaryAuthority

ResolverBase is a base class for implementations of IResolver which deals with a lot of the boilerplate of implementing all of the lookup methods.

def __init__(self): (source)

overridden in twisted.names.authority.FileAuthority, twisted.names.cache.CacheResolver, twisted.names.client.Resolver, twisted.names.hosts.Resolver, twisted.names.resolve.ResolverChain, twisted.names.root.Resolver, twisted.names.secondary.SecondaryAuthority

Undocumented

def exceptionForCode(self, responseCode): (source)

Convert a response code (one of the possible values of dns.Message.rCode to an exception instance representing it.

Present Since 10.0

def query(self, query, timeout=None): (source)

Dispatch query to the method which can handle its type.

Parameters	query	The DNS query being issued, to which a response is to be generated. (type: `twisted.names.dns.Query`)
Returns	A `Deferred` which fires with a three-tuple of lists of `twisted.names.dns.RRHeader` instances. The first element of the tuple gives answers. The second element of the tuple gives authorities. The third element of the tuple gives additional information. The `Deferred` may instead fail with one of the exceptions defined in `twisted.names.error` or with `NotImplementedError`.
