This class acts as a wrapper around an SFA interface manager module, but
can be used with any python module. The purpose of this class is raise a
- SfaNotImplemented exception if the a someone attepmts to use an attribute
+ SfaNotImplemented exception if someone attempts to use an attribute
(could be a callable) thats not available in the library by checking the
library using hasattr. This helps to communicate better errors messages
to the users and developers in the event that a specifiec operation
self.interface = interface
def __getattr__(self, method):
-
if not hasattr(self.manager, method):
raise SfaNotImplemented(method, self.interface)
return getattr(self.manager, method)
Returns the appropriate manager module for this interface.
Modules are usually found in sfa/managers/
