There's a bug in the last hunk anyway,
{
SwDocStat aStat(pDocShell->GetDoc()->GetDocStat());
if(aStat.bModified)
- pDocShell->GetDoc()->UpdateDocStat( aStat );
+ pDocShell->GetDoc()->UpdateDocStat();
i.e. the "aStat" is a copy so after the UpdateDocStat is called, it's an
unchanged copy, not a reference to an updated SwDocStat like it used to
be, so a line or two later nValue = aStat.nChar will be wrong.
Is there a specific problem you're trying to fix here ?
Looking through the DocStat stuff it looks a bit messy. Seems of it
appears to want to give access to the document statistics for a fast
query by some code that the stats need to be updated, and by other code
just to get the stats. And some bits fail to check for bModified and
force an update and some do. And the awesome rtf filter const_casts the
document doc stat and updates it directly.
If we want to refactor this then I suggest...
a) move "bModified" out of the SwDocStat and add something like bool
areStatsStale/statsNeedUpdating to IDocumentStatistics instead to query
this fact
b) have IDocumentStatistics::GetDocStat always return updated document
stats instead of having to get them, find out if they are stale and
update them if they are.
That would probably avoid the problems of needing to directly call
UpdateDocStat for the general case where someone just wants to get
up-to-date stats, but allow any special cases of calling UpdateDocStat
when areStatsStale is true in order to force update of fields that
display the doc stats.
