The public-facing ``Events`` serves as the base class for an event interface; its public attributes represent different kinds of events. These attributes are mirrored onto a ``_Dispatch`` class, which serves as a container for collections of listener functions. These collections are represented both at the class level of a particular ``_Dispatch`` class as well as within instances of ``_Dispatch``. i ( t absolute_importNi ( t utili ( t _JoinedListenert _EmptyListenert _ClsLevelDispatchc C@ s | j d o | d k S( Nt _t dispatch( t startswith( t name( ( sJ /home/tvault/.virtenv/lib/python2.7/site-packages/sqlalchemy/event/base.pyt _is_event_name s t _UnpickleDispatchc B@ s e Z d Z d Z RS( s Serializable callable that re-generates an instance of :class:`_Dispatch` given a particular :class:`.Events` subclass. c C@ sJ xC | j D], } d | j k r | j d j j | Sq Wt d d S( NR s* No class with a 'dispatch' member present.( t __mro__t __dict__t dispatch_clst _for_classt AttributeError( t selft _instance_clst cls( ( sJ /home/tvault/.virtenv/lib/python2.7/site-packages/sqlalchemy/event/base.pyt __call__' s ( t __name__t __module__t __doc__R ( ( ( sJ /home/tvault/.virtenv/lib/python2.7/site-packages/sqlalchemy/event/base.pyR ! s t _Dispatchc B@ s e Z d Z d Z e j Z d d Z d Z e d Z d Z d Z e d Z d Z d Z e d Z d Z RS( s; Mirror the event listening definitions of an Events class with listener collections. Classes which define a "dispatch" member will return a non-instantiated :class:`._Dispatch` subclass when the member is accessed at the class level. When the "dispatch" member is accessed at the instance level of its owner, an instance of the :class:`._Dispatch` class is returned. A :class:`._Dispatch` class is generated for each :class:`.Events` class defined, by the :func:`._create_dispatcher_class` function. The original :class:`.Events` classes remain untouched. This decouples the construction of :class:`.Events` subclasses from the implementation used by the event internals, and allows inspecting tools like Sphinx to work in an unsurprising way against the public API. t _parentR R t _empty_listenersc @ s} | | _ | _ rp y | j | _ Wqy t k rl t f d | j D | _ | j <qy Xn i | _ d S( Nc 3@ s' | ] } | j t | f Vq d S( N( R R ( t .0t ls( t instance_cls( sJ /home/tvault/.virtenv/lib/python2.7/site-packages/sqlalchemy/event/base.pys <genexpr>S s ( R R t _empty_listener_regR t KeyErrort dictt _event_descriptors( R t parentR ( ( R sJ /home/tvault/.virtenv/lib/python2.7/site-packages/sqlalchemy/event/base.pyt __init__J s %c C@ sL y | j | } Wn t k r0 t | n Xt | | j | | Sd S( N( R R R t setattrR ( R R R ( ( sJ /home/tvault/.virtenv/lib/python2.7/site-packages/sqlalchemy/event/base.pyt __getattr__Y s c c@ s&
