HSSFRequest
public HSSFRequest()
- Creates a new instance of HSSFRequest
addListener
public void addListener(HSSFListener lsnr,
short sid)
- add an event listener for a particular record type. The trick is you have to know
what the records are for or just start with our examples and build on them. Alternatively,
you CAN call addListenerForAllRecords and you'll recieve ALL record events in one listener,
but if you like to squeeze every last byte of efficiency out of life you my not like this.
(its sure as heck what I plan to do)
- Parameters:
lsnr
- for the eventsid
- identifier for the record type this is the .sid static member on the individual records
for example req.addListener(myListener, BOFRecord.sid)- See Also:
addListenerForAllRecords(HSSFListener)
addListenerForAllRecords
public void addListenerForAllRecords(HSSFListener lsnr)
- This is the equivilent of calling addListener(myListener, sid) for EVERY
record in the org.apache.poi.hssf.record package. This is for lazy
people like me. You can call this more than once with more than one listener, but
that seems like a bad thing to do from a practice-perspective unless you have a
compelling reason to do so (like maybe you send the event two places or log it or
something?).
- Parameters:
lsnr
- a single listener to associate with ALL records
processRecord
protected short processRecord(Record rec)
throws HSSFUserException
- Called by HSSFEventFactory, passes the Record to each listener associated with
a record.sid.
