class ScopedRegistry(Generic[_T]): (source)

Known subclasses: sqlalchemy.util._collections.ThreadLocalRegistry

View In Hierarchy

A Registry that can store one or multiple instances of a single class on the basis of a "scope" function. The object implements ``__call__`` as the "getter", so by calling ``myregistry()`` the contained object is returned for the current scope. :param createfunc: a callable that returns a new object to be placed in the registry :param scopefunc: a callable that will return a key to store/retrieve an object.

Method __call__ Undocumented
Method __init__ Construct a new :class:`.ScopedRegistry`.
Method clear Clear the current scope, if any.
Method has Return True if an object is present in the current scope.
Method set Set the value for the current scope.
