This is probably mainly going to Flavio:
I've tried a different approach to solving my problem described
in earlier posts and this time I have the following issue:
If I do an intersection (whether with iterator->next($span)
or $spanset->intersection($span) or even
$spanset->as_list($span)), I get a SpanSet that can have,
depending on where the intersection span starts and ends, a cut
first span and a cut last span:
|----| |----| |----| |----| # Source SpanSet
|----------------| # intersection Span
|--| |----| |--| # Resulting SpanSet
what I actually need is a set of unmodified spans intersected by
that span:
|----| |----| |----| # Wanted resulting SpanSet
I do understand that this behaviour is wanted by some
applications but in mine, I can't use the resulting spanset.
One solution to my problem would be to check the first and
the last Span in my resulting SpanSet for its length and correct
it when necessary. But I find that solution rather ugly.
So I wonder, if you could point me to a better solution.
Thanks very much,
Reinhold
