See the documentation of the Message class for a complete description of the keyring dictionary. *zone*, a ``dns.name.Name``, ``str``, or ``None``, the zone which is being updated. ``None`` should only be used by dnspython's message constructors, as a zone is required for the convenience methods like ``add()``, ``replace()``, etc. *rdclass*, an ``int`` or ``str``, the class of the zone. The *keyring*, *keyname*, and *keyalgorithm* parameters are passed to ``use_tsig()``; see its documentation for details. )r T)ZcreateZ force_uniqueN)� algorithm)�super�__init__�flags�dnsZopcodeZto_flagsr � isinstance�str�name� from_text�origin� rdataclass� RdataClass�make� zone_rdclass� find_rrsetr � rdatatype�SOAZuse_tsig)�selfr r r r r r �� __class__r r r 1 s$ �zUpdateMessage.__init__)�returnc C s | j d S )zThe zone section.r �Zsections�r/ r r r r \ s zUpdateMessage.zonec C s || j d< d S )Nr r3 �r/ �vr r r r a s c C s | j d S )zThe prerequisite section.r r3 r4 r r r � prerequisitee s zUpdateMessage.prerequisitec C s || j d< d S )Nr r3 r5 r r r r7 j s c C s | j d S )zThe update section.r r3 r4 r r r �updaten s zUpdateMessage.updatec C s || j d< d S )Nr r3 r5 r r r r8 s s c C sB |du r| j }|�� }| �||| j|j||dd�}|�||� dS )z&Add a single RR to the update section.NT)r8 �coversr, r+ �rdtype�add)r/ r% �ttl�rd�deleting�sectionr9 �rrsetr r r �_add_rrw s �zUpdateMessage._add_rrc G s t |t�rtj�|d�}t |d tjj�rf|D ]4}|rD| �||j� |D ]}| j ||j ||d� qHq.n�t |�}t |� d��}t |d tjj�r�|r�| �||d j� |D ]}| j ||||d� q�nVtjj�|� d��}|r�| �||� |D ],} tj�| j|| | j�}| j ||||d� q�dS )a� Add records. *replace* is the replacement mode.
