Description
It was originally planned that EntityManager::clear() would also support an optional argument - $entity -, which would remove only the reference to an existent entity (maybe also consider a new cascade to allow graph clearing) from UoW.
Currently, it's win or wall. You can't clear a specific portion of Entities.
I implemented this (https://github.com/doctrine/doctrine2/pull/104) but forgot to consider also cascade detach. What do you think about adding an additional parameter $entityName to both cascadeDetach() and doDetach()?
