Subject HSSF: Middle-ground API for reading an Excel spreadsheet
Date Tue, 22 Jan 2008 22:22:25 GMT
Hi all.

I was wondering if anyone had experimented with doing lazy parsing via the 
eventusermodel interface.  I've had an attempt at it myself but am running 
into various troubles.

The first one which is really problematic is that once I get a FormulaRecord, 
I can't find a way to convert that into the formula string.  Thankfully 
getting the value result is relatively simple.

Have the HSSF developers considered making an API half way between usermodel 
and eventusermodel, which can return HSSFCell instances one at a time without 
instantiating the entire spreadsheet?  It would be a really nice thing for 
saving memory.  (Although an implementation of the records which doesn't 
create copies of everything in memory would probably solve the memory 
problems almost as well.)
