Class InternalWorkbook

    java.lang.Object
      org.apache.poi.hssf.model.InternalWorkbook

    @Internal
    public final class InternalWorkbook

extends java.lang.Object

Low level model implementation of a Workbook. Provides creational methods for settings and objects contained in the workbook object.

This file contains the low level binary records starting at the workbook's BOF and ending with the workbook's EOF. Use HSSFWorkbook for a high level representation.

The structures of the highlevel API use references to this to perform most of their operations. Its probably unwise to use these low level structures directly unless you really know what you're doing. I recommend you read the Microsoft Excel 97 Developer's Kit (Microsoft Press) and the documentation at http://sc.openoffice.org/excelfileformat.pdf before even attempting to use this.
