STON: SortedCollection Bug?

Administrator

I serialized aSortedCollection with a sort block comparing via a #startTime
message on the domain objects. When I attempted to materialize it, I got an
error that my domain objects don't understand #<=. It seems that the
elements are being loaded before the sort block.

Re: STON: SortedCollection Bug?

STON cannot serialise block closures. You would have to get creative to make this work.

For SortedCollection, it would only work without a sort block.

STON fromString: (STON toString: #(1 2 3) asSortedCollection).

Oops, sorry. I see that now:
https://github.com/svenvc/ston/blob/master/ston-paper.md#limitations

I wonder, in this case, there are no references in the block to any objects
except its own arguments. Would it be possible to support that limited case?
(I don't need it for myself, just pondering out loud)

Yeah, I was thinking along the same lines, especially clean block might be doable.

I'll mark this as todo and think about it a bit.
