[OpenMap Users] Performance considerations

Hi all,

My app has to load large shape files (EsriPlugin) and, doing so, it has
its performances dramatically decreased.

I tried to profile it and the result if this tracing shows that more
than 96% the CPU time is spent in the following sequence:

getEsrilGraphicList() -> getGeometry() -> <CUT> ->
DrawingAttributes.setFrom().

More precisely, it is the call to resetGUI() inside setFrom() whih takes
the CPU time. It's obviously because this member call GUI related stuff
which is time consuming.

As I don't have knownledge enough of the complete OpenMap architecture,
I just tried to remove the call to resetGUI() in
com.bbn.openmap.omGraphics.DrawingAttributes.setFrom(...).

I was surprised that my app still works correctly and that this change
dramatically improves its performances (my layers are now loaded in a
few seconds instead of several minutes!)

My question is thus simple: is the call to resetGUI() needed there? I
have the impression that it is only needed by getColorAndLineGUI() which
also calls resetGUI()...
