The dependency relationships are stored in an ``adjacency_list`` that maps distributions to a list of ``(other, label)`` tuples where ``other`` is a distribution and the edge is labeled with ``label`` (i.e. the version specifier, if such was provided). Also, for more efficient traversal, for every distribution ``x``, a list of predecessors is kept in ``reverse_list[x]``. An edge from distribution ``a`` to distribution ``b`` means that ``a`` depends on ``b``. If any missing dependencies are found, they are stored in ``missing``, which is a dictionary that maps distributions to a list of requirements that were not provided by any other distributions. c C s i | _ i | _ i | _ d S( N( u adjacency_listu reverse_listu missing( u self( ( u5 /tmp/pip-zej_zi-build/pip/_vendor/distlib/database.pyu __init__# s u DependencyGraph.__init__c C s g | j | <g | j | <d S( u� Add the *distribution* to the graph. :type distribution: :class:`distutils2.database.InstalledDistribution` or :class:`distutils2.database.EggInfoDistribution` N( u adjacency_listu reverse_list( u selfu distribution( ( u5 /tmp/pip-zej_zi-build/pip/_vendor/distlib/database.pyu add_distribution( s u DependencyGraph.add_distributionc C sH | j | j | | f � | | j | k rD | j | j | � n d S( u� Add an edge from distribution *x* to distribution *y* with the given *label*. :type x: :class:`distutils2.database.InstalledDistribution` or :class:`distutils2.database.EggInfoDistribution` :type y: :class:`distutils2.database.InstalledDistribution` or :class:`distutils2.database.EggInfoDistribution` :type label: ``str`` or ``None`` N( u adjacency_listu appendu reverse_list( u selfu xu yu label( ( u5 /tmp/pip-zej_zi-build/pip/_vendor/distlib/database.pyu add_edge2 s u DependencyGraph.add_edgec C s3 t j d | | � | j j | g � j | � d S( u Add a missing *requirement* for the given *distribution*. :type distribution: :class:`distutils2.database.InstalledDistribution` or :class:`distutils2.database.EggInfoDistribution` :type requirement: ``str`` u %s missing %rN( u loggeru debugu missingu setdefaultu append( u selfu distributionu requirement( ( u5 /tmp/pip-zej_zi-build/pip/_vendor/distlib/database.pyu add_missingA s u DependencyGraph.add_missingc C s d | j | j f S( Nu %s %s( u nameu version( u selfu dist( ( u5 /tmp/pip-zej_zi-build/pip/_vendor/distlib/database.pyu _repr_distL s u DependencyGraph._repr_disti c C s� | j | � g } x� | j | D]� \ } } | j | � } | d k rZ d | | f } n | j d | t | � � | j | | d � } | j d � } | j | d d � � q Wd j | � S( u Prints only a subgraphu %s [%s]u i u N( u _repr_distu adjacency_listu Noneu appendu stru repr_nodeu splitu extendu join( u selfu distu levelu outputu otheru labelu suboutputu subs( ( u5 /tmp/pip-zej_zi-build/pip/_vendor/distlib/database.pyu repr_nodeO s u DependencyGraph.repr_nodec C sR g } | j d � x� | j j � D]� \ } } t | � d k rX | rX | j | � n x` | D]X \ } } | d k r� | j d | j | j | f � q_ | j d | j | j f � q_ Wq# W| rAt | � d k rA| j d � | j d � | j d � x/ | D]' } | j d | j � | j d � qW| j d � n | j d � d S( u9 Writes a DOT output for the graph to the provided file *f*.
