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(tabsolute_importi(tutili(t_JoinedDispatchDescriptort_EmptyListenert_DispatchDescriptorcC@s|jdƒ o|dkS(Nt_tdispatch(t startswith(tname((s[/var/www/send.findwatt.com/datamanager/lib/python2.7/site-packages/sqlalchemy/event/base.pyt_is_event_namest_UnpickleDispatchcB@seZdZd„ZRS(sSerializable callable that re-generates an instance of :class:`_Dispatch` given a particular :class:`.Events` subclass. cC@sGx@|jD])}d|jkr |jdj|ƒSq Wtdƒ‚dS(NRs*No class with a 'dispatch' member present.(t__mro__t__dict__t dispatch_clstAttributeError(tselft _parent_clstcls((s[/var/www/send.findwatt.com/datamanager/lib/python2.7/site-packages/sqlalchemy/event/base.pyt__call__%s(t__name__t __module__t__doc__R(((s[/var/www/send.findwatt.com/datamanager/lib/python2.7/site-packages/sqlalchemy/event/base.pyR st _DispatchcB@s_eZdZdZd„Zejd„ƒZd„Z d„Z e d„Z ej d„ƒZRS(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. cC@s ||_dS(N(R(RR((s[/var/www/send.findwatt.com/datamanager/lib/python2.7/site-packages/sqlalchemy/event/base.pyt__init__EscC@s |jjS(N(t_eventst_listen(R((s[/var/www/send.findwatt.com/datamanager/lib/python2.7/site-packages/sqlalchemy/event/base.pyRHscC@s‰d|jjkrytd|jjt|jfiƒ}x0t|ƒD]"}t||jt|jƒƒqDW||j_ n|j ||ƒS(s‘Create a 'join' of this :class:`._Dispatch` and another.
