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_importNi(t_ClsLevelDispatch(t_EmptyListener(t_JoinedListeneri(tutilcC@s|jdƒ o|dkS(Nt_tdispatch(t startswith(tname((sH/opt/alt/python27/lib64/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@sJxC|jD],}d|jkr |jdjj|ƒSq Wtdƒ‚dS(NRs*No class with a 'dispatch' member present.(t__mro__t__dict__Rt _for_classtAttributeError(tselft _instance_clstcls((sH/opt/alt/python27/lib64/python2.7/site-packages/sqlalchemy/event/base.pyt__call__)s  (t__name__t __module__t__doc__R(((sH/opt/alt/python27/lib64/python2.7/site-packages/sqlalchemy/event/base.pyR #st _DispatchcB@sŒeZdZdZejƒZdd„Zd„Z e d„ƒZ e d„ƒZ d „Z d „Zd „Zd „Zed „Zd„ZRS(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_parentRR t_empty_listenersc@sw||_ˆ|_ˆrjy|jˆ|_Wqstk rf‡fd†|jDƒ|_|jˆXs (RRt_empty_listener_regRtKeyErrort_event_descriptors(RtparentR((RsH/opt/alt/python27/lib64/python2.7/site-packages/sqlalchemy/event/base.pyt__init__Ms    "cC@sLy|j|}Wntk r0t|ƒ‚nXt||j|ƒ|SdS(N(RRRtsetattrR(RRR((sH/opt/alt/python27/lib64/python2.7/site-packages/sqlalchemy/event/base.pyt __getattr__^s  cc@s&x|jD]}t||ƒVq WdS(N(t _event_namestgetattr(Rtk((sH/opt/alt/python27/lib64/python2.7/site-packages/sqlalchemy/event/base.pyRiscC@s |jjS(N(t_eventst_listen(R((sH/opt/alt/python27/lib64/python2.7/site-packages/sqlalchemy/event/base.pyR'pscC@s|j||ƒS(N(t __class__(RR((sH/opt/alt/python27/lib64/python2.7/site-packages/sqlalchemy/event/base.pyR tscC@s|j}|j|ƒS(N(R(R (RtinstanceR((sH/opt/alt/python27/lib64/python2.7/site-packages/sqlalchemy/event/base.pyt _for_instancews cC@sZd|jjkrJtd|jjtfi|jd6ƒ}||j_n|j||ƒS(s‘Create a 'join' of this :class:`._Dispatch` and another.
