Interface Summary

Interface	Description
HSSFListener	Interface for use with the HSSFRequest and HSSFEventFactory.

Class Summary

Class	Description
AbortableHSSFListener	Abstract class for use with the HSSFRequest and HSSFEventFactory, which allows for the halting of processing.
EventWorkbookBuilder	When working with the EventUserModel, if you want to process formulas, you need an instance of InternalWorkbook to pass to a HSSFWorkbook, to finally give to HSSFFormulaParser, and this will build you stub ones.
EventWorkbookBuilder.SheetRecordCollectingListener	A wrapping HSSFListener which will collect BoundSheetRecords and ExternSheetRecords as they go past, so you can create a Stub InternalWorkbook from them once required.
FormatTrackingHSSFListener	A proxy HSSFListener that keeps track of the document formatting records, and provides an easy way to look up the format strings used by cells from their ids.
HSSFEventFactory	Low level event based HSSF reader.
HSSFRequest	An HSSFRequest object should be constructed registering an instance or multiple instances of HSSFListener with each Record.sid you wish to listen for.
MissingRecordAwareHSSFListener	A HSSFListener which tracks rows and columns, and will trigger your HSSFListener for all rows and cells, even the ones that aren't actually stored in the file.

Exception Summary

Exception	Description
HSSFUserException	This exception is provided as a way for API users to throw exceptions from their event handling code.

Package org.apache.poi.hssf.eventusermodel Description

HSSF eventmodel Package provides an event-based API for reading HSSF files.

The event model can read XLS files with a very small memory footprint. For writing you still have to use the usermodel. The eventmodel is to the usermodel what SAX is to DOM.
