b.d.DirectoryServiceRegistry(registry.Registry) : class documentation

Part of bzrlib.directory_service View In Hierarchy

This object maintains and uses a list of directory services.

Directory services may be registered via the standard Registry methods. They will be invoked if their key is a prefix of the supplied URL.

Each item registered should be a factory of objects that provide a look_up method, as invoked by dereference. Specifically, look_up should accept a name and URL, and return a URL.

Method dereference Dereference a supplied URL if possible.
