Overridden by a subclass to test for conflicting factories.

def _collect_management_factories_for(self, cls): (source) ¶

Return a collection of factories in play or specified for a hierarchy. Traverses the entire inheritance graph of a cls and returns a collection of instrumentation factories for those classes. Factories are extracted from active ClassManagers, if available, otherwise instrumentation_finders is consulted.
