They can represent address ranges that do not fall on strict bit mask boundaries. They are suitable for use in configuration files, being more obvious and readable than their CIDR counterparts, especially for admins and end users with little or no networking knowledge or experience. All CIDR addresses can always be represented as IP globs but the reverse is not always true. �_globc s6 t |�\}}tt| �j||� t| j| j�d | _d S )Nr )r% �superr4 �__init__r1 �_start�_end�glob)�selfr r- r. )� __class__r r r7 s zIPGlob.__init__c s t t| �j� S )z-:return: Pickled state of an `IPGlob` object.)r6 r4 � __getstate__)r; )r< r r r= s zIPGlob.__getstate__c s( t t| �j|� t| j| j�d | _dS )z>:param state: data used to unpickle a pickled `IPGlob` object.r N)r6 r4 � __setstate__r1 r8 r9 r: )r; �state)r< r r r> # s zIPGlob.__setstate__c C s | j S )N)r5 )r; r r r � _get_glob( s zIPGlob._get_globc C s( t |�\| _| _t| j| j�d | _d S )Nr )r% r8 r9 r1 r5 )r; r r r r � _set_glob+ s zIPGlob._set_globNz-an arbitrary IP address range in glob format.c C s d| j S )z3:return: IP glob in common representational format.z%s)r: )r; r r r �__str__2 s zIPGlob.__str__c C s d| j j| jf S )z8:return: Python statement to create an equivalent objectz%s('%s'))r< �__name__r: )r; r r r �__repr__6 s zIPGlob.__repr__)r5 )rC � __module__� __qualname__�__doc__� __slots__r7 r= r> r@ rA �propertyr: rB rD � __classcell__r r )r< r r4 � s - r4 N)rG Z netaddr.corer r Z netaddr.ipr r r r Znetaddr.compatr r r% r& r1 r2 r3 r4 r r r r �<module> s 6 J
