Hi All
About 10 years after someone first asked for it, we've finally gotten
in-place-write and write-to-file available for HSSF! (And HSLF too)
This means that if you open a HSSFWorkbook or HSLFSlideShowImpl from a
File, in read-write mode (not read-only, which is the default), you can
write your changes back to the same open file without issue or error. You
can also write out to a brand new file, without having to mess with
OutputStreams (should be faster)
The main two methods for this, available for HSSF and HSLF, are:
https://poi.apache.org/apidocs/org/apache/poi/POIDocument.html#write()
https://poi.apache.org/apidocs/org/apache/poi/POIDocument.html#write(java.io.File)
So, two requests:
* Please test this for HSLF + HSSF!
* Please help us document this on the site, have examples etc
Assuming feedback from HSSF + HSLF suggests we've gone about it the right
way, we can then roll it out to HWPF and the OPC / X??F classes too
