-"""
-The :class:`~openstack.service_filter.ServiceFilter` is the base class
-for service identifiers and user service preferences.  Each
-:class:`~openstack.resource.Resource` has a service identifier to
-associate the resource with a service.  An example of a service identifier
-would be ``openstack.compute.compute_service.ComputeService``.
-The service preference and the service identifier are joined to create a
-filter to match a service.
-
-Examples
---------
-
-The :class:`~openstack.service_filter.ServiceFilter` class can be built
-with a service type, interface, region, name, and version.
-
-Create a service filter
-~~~~~~~~~~~~~~~~~~~~~~~
-
-Create a compute service and service preference. Join the services
-and match::
-
-    from openstack import service_filter
-    from openstack.compute import compute_service
-    default = compute_service.ComputeService()
-    preference = service_filter.ServiceFilter('compute', version='v2')
-    result = preference.join(default)
-    matches = (result.match_service_type('compute') and
-               result.match_service_name('Hal9000') and
-               result.match_region('DiscoveryOne') and
-               result.match_interface('public'))
-    print(str(result))
-    print("matches=" + str(matches))
-
-The resulting output from the code::
-
-    service_type=compute,interface=public,version=v2
-    matches=True
