The Acquisition base classes (such as Acquisition.Implicit) override getattr() handling and automatically handle the wrapping of the resulting object when an attribute is accessed via getattr().
<note> This isn't quite right. ExtensionClass checks for an '__of__' method on a sub-object retrieved through an attribute access. The '__of__' method, is defined for the sub-object, is called to obtain the sub-object in the context of the container. Acquisition.Implicit defined '__of__', not '__getattr__'. The '__of__' protocol is *also* used for things like user-defined method types and computed attributes. </note> Jim -- Jim Fulton mailto:jim@digicool.com Python Powered!
