what the code "return cls()" meaning
I am a newcomer of openstack and python. When I read the code in file nova-2011.3\nova\api\openstack__init__.py
I found these lines
class APIRouter(base_wsgi.Router): """ Routes requests on the OpenStack API to the appropriate controller and method. """
@classmethod
def factory(cls, global_config, **local_config):
"""Simple paste factory, :class:`nova.wsgi.Router` doesn't have one"""
return cls()
My question is: what the code "return cls()" means in the factory() class method? where to find the factory() method body?
Please help me, thx.
