Class: Spreadsheet_Excel_Writer_BIFFwriter - X-Ref

Class for writing Excel BIFF records.

From "MICROSOFT EXCEL BINARY FILE FORMAT" by Mark O'Brien (Microsoft Corporation):

BIFF (BInary File Format) is the file format in which Excel documents are
saved on disk. A BIFF file is a complete description of an Excel document.
BIFF files consist of sequences of variable-length records. There are many
different types of BIFF records. For example, one record type describes a
formula entered into a cell; one describes the size and location of a
window into a document; another describes a picture format.

Spreadsheet_Excel_Writer_BIFFwriter() X-Ref

recalculating it for each call to new().

_storeEof() X-Ref

_addContinue($data) X-Ref

Excel limits the size of BIFF records. In Excel 5 the limit is 2084 bytes. In
Excel 97 the limit is 8228 bytes. Records that are longer than these limits
must be split up into CONTINUE blocks.

This function takes a long BIFF record and inserts CONTINUE records as
necessary.

param: string $data The original binary data to be written
return: string A very convenient string of continue blocks
