State persistance and passing into and out of steps

[seertenedos]

If i pass an object into a step from state and maniputate the object in the step do i need to map that object in output after that step back to state for it to be persisted or will it still be saved as a reference was passed in originally and that was what was changed. Just trying to get around declearing output calls if i don't need to,. It seems to work but currently only testing in memory so it could be different when persisting to a proper store.
