event model and writing

["KHZ (SAW)" <ka...@sawag.com>]

Hi world.
 
I always was using the conventional way. Now I've to compare several
things.
 
It looks like just reading can be done in a memory efficient way
receiving events while POI traverses the Excel documents and notifies
records of various types.
 
If writing has to be performed I just can use the event model at the
reading side and at the writing side I just can use the conventional
way. So memory saving just can be done at the reading side. Additionally
information has to be copied from the records to e.g. HSSFWorkbook
HSSFSheet, HSSFRow, HSSFCell, ... .
 
Is this right? Or are there special cases where also writing can be done
in a memory efficient way?
