To avoid potential thread safety issues for imports that are deferred in a function, like https://bugs.python.org/issue38884, these modules are added to the system module cache by importing them after the packages has finished initialization. A global instance is provided under the name :attr:`.preloaded`. Use the function :func:`.preload_module` to register modules to load and :meth:`.import_prefix` to load all the modules that start with the given path. While the modules are loaded in the global module cache, it's advisable to access them using :attr:`.preloaded` to ensure that it was actually registered. Each registered module is added to the instance ``__dict__`` in the form `_`, omitting ``sqlalchemy`` from the package name. Example: ``sqlalchemy.sql.util`` becomes ``preloaded.sql_util``. ú sqlalchemy.cCstƒ|_||_dS©N)ÚsetÚmodule_registryÚprefix)Úselfr ©r úP/var/www/html/gps/gps/lib/python3.10/site-packages/sqlalchemy/util/_preloaded.pyÚ__init__&s z_ModuleRegistry.__init__cGs|j |¡dd„S)z¿Adds the specified modules to the list to load.
