Using the Zope3 API directly is strongly recommended. Everything you need is in the top-level of the zope.interface package, e.g.:: from zope.interface import Interface, implementer class IFoo(Interface): pass @implementer(IFoo) class Foo: pass print(IFoo.implementedBy(Foo)) # True print(IFoo.providedBy(Foo())) # True L{twisted.python.components.registerAdapter} from this module may be used to add to Twisted's global adapter registry. L{twisted.python.components.proxyForInterface} is a factory for classes which allow access to only the parts of another class defined by a specified interface. i ( t divisiont absolute_importt print_function( t interfacet declarations( t AdapterRegistry( t NativeStringIO( t reflect( t _oldStylec G` s� t } | s t d � � t | t j � s< t j | � } n xL | D]D } | j | g | � } | d k rC t rC t d | f � � qC qC Wx' | D] } | j | g | d | � q� Wd S( s Register an adapter class.

If such an adapter has already been created, retrieve it from the cache that this instance keeps of all its adapters. Adapters created through this mechanism may safely store system-specific state.
