From ##32

Also it might be useful to have a delExisting method like in LD-PATCH and possibly a putNew (like addNew) method?

jacoscaz commented 7 years ago

To clarify:

putNew acts like put but throws for quads already present in the store.
delExisting acts like del but throws for quads that are not present in the store.

Another way to do this could be through a dedicated opts like opts.throwIf(Not)Exist.

jmatsushita commented 7 years ago

Yes that's what I meant. Dedicated opts would indeed work too!

jacoscaz commented 7 years ago

What about stream? Would this need to support streams (via .on('error', (DuplicateQuadError err) => {}))?

jacoscaz commented 6 years ago

@jmatsushita are you still interested in this feature?

Cleaning up old issues, will reopen a new one if needed.
