API to get all revisions affecting a NodeDocument

[Robert Munteanu]

Hi,

For a NodeDocument I'd like to know which revisions it is linked to  (
in order to infer the commits ).

I've looked at NodeDocument#getLastRev ( but not all documents have the
_lastRev field defined ). I've also tried to to use
DocumentNodeStore#getHeadRevision , but the revision I get doesn't work
with NodeDocument#getCommitRootPath .

Is there an API for retrieving the revisions that affect a
NodeDocument?

Thanks,

Robert
