Class ProtectRecord

java.lang.Object
loci.poi.hssf.record.Record
loci.poi.hssf.record.ProtectRecord

public class ProtectRecord extends Record
Title: Protect Record

Description: defines whether a sheet or workbook is protected (HSSF DOES NOT SUPPORT ENCRYPTION)

(kindly ask the US government to stop having arcane stupid encryption laws and we'll support it)

(after all terrorists will all use US-legal encrypton right??)

HSSF now supports the simple "protected" sheets (where they are not encrypted and open office et al ignore the password record entirely). REFERENCE: PG 373 Microsoft Excel 97 Developer's Kit (ISBN: 1-57231-498-2)
