There was a problem hiding this comment.
LGTM, but I suggest to add an assertion that this will actually be called, see here for an example:
https://github.com/arangodb/arangodb/blob/bug-fix/add-initialize-cursor-to-distinct-collect-executor/arangod/Aql/ExecutionBlockImpl.cpp#L369
|
@goedderz : ok, will try to add this, though it feels a bit strange to have to modify a different file (ExecutionBlockImpl.cpp) and add assertions there if I modify a specialization. |
Yes, I agree. Perhaps I can find a better way to do that. |
