The :mod:`sqlalchemy.ext.instrumentation` package provides for alternate systems of class instrumentation within the ORM. Class instrumentation refers to how the ORM places attributes on the class which maintain data and track changes to that data, as well as event hooks installed on the class. .. note:: The extension package is provided for the benefit of integration with other object management packages, which already perform their own instrumentation. It is not intended for general use. For examples of how the instrumentation extension is used, see the example :ref:`examples_instrumentation`. iNi(tutil(t attributes(tbase(t collections(texc(tinstrumentation(t_default_dict_getter(t_default_manager_getter(t_default_state_getter(t ClassManager(tInstrumentationFactoryt__sa_instrumentation_manager__cCst|tdS(s;Find user-specified instrumentation management for a class.N(tgetattrtINSTRUMENTATION_MANAGERtNone(tcls((sQ/opt/alt/python27/lib64/python2.7/site-packages/sqlalchemy/ext/instrumentation.pyt%find_native_user_instrumentation_hook;stExtendedInstrumentationRegistrycBseZdZejZejZejZeZ dZ dZ dZ dZ dZdZdZdZRS( sExtends :class:`.InstrumentationFactory` with additional bookkeeping, to accommodate multiple types of class managers. cCsMxFtD]:}||}|dk r|j||}||fSqWdSdS(N(NN(tinstrumentation_findersRt_extended_class_manager(tselftclass_tfindertfactorytmanager((sQ/opt/alt/python27/lib64/python2.7/site-packages/sqlalchemy/ext/instrumentation.pyt_locate_extended_factory]s    cCsG|j|j|g}|rCtd|jt|fndS(NsRmultiple instrumentation implementations specified in %s inheritance hierarchy: %r(t!_collect_management_factories_fort differencet TypeErrort__name__tlist(RRRtexisting_factories((sQ/opt/alt/python27/lib64/python2.7/site-packages/sqlalchemy/ext/instrumentation.pyt_check_conflictsfs  cCs||}t|ts-t||}n|tkrV|j rVt|_tn|j|j|<|j|j |<|j |j |<|S(N( t isinstanceR t_ClassInstrumentationAdaptert _extendedtTruet_install_instrumented_lookupstmanager_gettert_manager_finderst state_gettert_state_finderst dict_gettert _dict_finders(RRRR((sQ/opt/alt/python27/lib64/python2.7/site-packages/sqlalchemy/ext/instrumentation.pyRqs   cCstj|}t}x||D]t}|j|}|dk rS|j|jqx0tD]"}||}|dk rZPqZqZWd}|j|qW|jd|S(scReturn a collection of factories in play or specified for a hierarchy.
