save
open override fun saveAllReturningCanonical(propositions: Collection<Proposition>): PropositionPersistenceResult
The same, keeping what each proposition landed on. Overridden for the same reason saveAll is: by delegate forwards an interface default straight to the delegate, so the default body would run the delegate's save and this decorator would emit nothing.
Return
The stored proposition for each input, and the input-id to stored-id mapping.
Parameters
propositions
The propositions to persist.
