I've had an experiment with a few ideas, and the one I like the best is one
which replaces my LinkedSegment objects with ordinary Segment ones, and has a
SegmentLinker instead of a LinkedSegmentReference. It uses Yves idea of a
Segment being linked when it has a particular pointer set to something non-null
(a SegmentLinker I've called it), but there is only one SegmentLinker per
linked
Segment group. The SegmentLinker sorts out all of the inter-segment
coordination. It works just as well as my original one, but is nice and simple
an doesn't close editors when you link stuff.
I'm aiming to get something committed this week, need to iron out a few probs,
tidy up the code, put all my broken serialisation and transposition back
together then we should be good to go with doing something for repeating
segments.
Cheers,
Ian.
