[TYPO3-mvc] Persist Object only if dirty

[Philipp]

Hey, a simple question about extbase:
When adding an object with repository->update(object) and calling persistAll on the persistenceManager

Does extbase somewhere check if the entity was updated or do i have to call _isDirty() manually before making update?

i browsed through the code - looks like i have to do it by my own, just wanted to be sure.

kind regards.
