A Zone is a mapping from names to nodes. The zone object may be treated like a Python dictionary, e.g. zone[name] will retrieve the node associated with that name. The I{name} may be a dns.name.Name object, or it may be a string. In the either case, if the name is relative it is treated as relative to the origin of the zone. @ivar rdclass: The zone's rdata class; the default is class IN. @type rdclass: int @ivar origin: The origin of the zone. @type origin: dns.name.Name object @ivar nodes: A dictionary mapping the names of nodes in the zone to the nodes themselves. @type nodes: dict @ivar relativize: should names in the zone be relativized? @type relativize: bool @cvar node_factory: the factory used to create a new node @type node_factory: class or callable t rdclasst origint nodest relativizec C s( | | _ | | _ i | _ | | _ d S( s� Initialize a zone object. @param origin: The origin of the zone. @type origin: dns.name.Name object @param rdclass: The zone's rdata class; the default is class IN. @type rdclass: intN( R R R R ( t selfR R R ( ( s. /usr/lib64/python2.7/site-packages/dns/zone.pyt __init__R s c C sQ t | t � s t S| j | j k sI | j | j k sI | j | j k rM t St S( si Two zones are equal if they have the same origin, class, and nodes. @rtype: bool ( t isinstanceR t FalseR R R t True( R t other( ( s. /usr/lib64/python2.7/site-packages/dns/zone.pyt __eq___ s c C s | j | � S( s6 Are two zones not equal? @rtype: bool ( R ( R R ( ( s. /usr/lib64/python2.7/site-packages/dns/zone.pyt __ne__m s c C s� t | t t f � r- t j j | d � } n$ t | t j j � sQ t d � � n | j � r� | j | j � s~ t d � � n | j r� | j | j � } q� n | S( Ns0 name parameter must be convertable to a DNS names5 name parameter must be a subdomain of the zone origin( R t strt unicodet dnst namet from_textt Nonet Namet KeyErrort is_absolutet is_subdomainR R ( R R ( ( s. /usr/lib64/python2.7/site-packages/dns/zone.pyt _validate_namet s c C s | j | � } | j | S( N( R R ( R t key( ( s. /usr/lib64/python2.7/site-packages/dns/zone.pyt __getitem__� s c C s | j | � } | | j | <d S( N( R R ( R R! t value( ( s. /usr/lib64/python2.7/site-packages/dns/zone.pyt __setitem__� s c C s | j | � } | j | =d S( N( R R ( R R!
