public abstract class FormattedDiskPage
Represents an FKP data structure. This data structure is used to store the
grpprls of the paragraph and character properties of the document. A grpprl
is a list of sprms(decompression operations) to perform on a parent style.
The style properties for paragraph and character runs
are stored in fkps. There are PAP fkps for paragraph properties and CHP fkps
for character run properties. The first part of the fkp for both CHP and PAP
fkps consists of an array of 4 byte int offsets in the main stream for that
Paragraph's or Character run's text. The ending offset is the next
value in the array. For example, if an fkp has X number of Paragraph's
stored in it then there are (x + 1) 4 byte ints in the beginning array. The
number X is determined by the last byte in a 512 byte fkp.
CHP and PAP fkps also store the compressed styles(grpprl) that correspond to
the offsets on the front of the fkp. The offset of the grpprls is determined
differently for CHP fkps and PAP fkps.
