This module is usually not directly visible to user applications, but defines a large part of the ORM's interactivity. instrumentation.py deals with registration of end-user classes for state tracking. It interacts closely with state.py and attributes.py which establish per-instance and per-class-attribute instrumentation, respectively. The class instrumentation system can be customized on a per-class or global basis using the :mod:`sqlalchemy.ext.instrumentation` module, which provides the means to build and specify alternate instrumentation forms. .. versionchanged: 0.8 The instrumentation extension system was moved out of the ORM and into the external :mod:`sqlalchemy.ext.instrumentation` package. When that package is imported, it installs itself within sqlalchemy.orm so that its more comprehensive resolution mechanics take effect. i(texct collectionst interfaceststatei(tutil(tbaset ClassManagercBsèeZdZejZejZd(Z e j Z d(Z d„Z d„Zd„Zed„ƒZejd„ƒZd(d„Zd„Zd„Zd „Zd „Zejd „ƒZd „Zd „Zejd„ƒZejd„ƒZejd„ƒZ e!d„Z"d„Z#d„Z$e!d„Z%d„Z&d„Z'd„Z(d„Z)d„Z*d„Z+d„Z,e!d„Z-d„Z.ed„ƒZ/d(d„Z0d(d „Z1d!„Z2d"„Z3d#„Z4d$„Z5e!d%„Z6d&„Z7e7Z8d'„Z9RS()s,tracks state information at the class level.cCs7||_i|_d|_i|_i|_gg|jjD]!}t|tƒr=t |ƒ^q=D]}|dk rb|^qb|_ x|j D]}|j |ƒqW|j j j||ƒx?|jD]4}t |ƒ}|dk rÄ|j j|j ƒqÄqÄW|jƒ|jƒd|jkr3tjd|ƒndS(Nt__del__s¦__del__() method on class %s will cause unreachable cycles and memory leaks, as SQLAlchemy instrumentation often creates reference cycles.
