public final class ExtSSTRecord
extends ContinuableRecord

Title: Extended Static String Table (0x00FF)

Description: This record is used for a quick lookup into the SST record. This record breaks the SST table into a set of buckets. The offsets to these buckets within the SST record are kept as well as the position relative to the start of the SST record.

Method Detail

setNumStringsPerBucket

public void setNumStringsPerBucket(short numStrings)

toString

public String toString()

Description copied from class: Record

get a string representation of the record (for biffview/debugging)

Overrides:

toString in class Record

serialize

public void serialize(ContinuableRecordOutput out)

Description copied from class: ContinuableRecord

Serializes this record's content to the supplied data output.

The standard BIFF header (ushort sid, ushort size) has been handled by the superclass, so only BIFF data should be written by this method. Simple data types can be written with the standard LittleEndianOutput methods. Methods from ContinuableRecordOutput can be used to serialize strings (with ContinueRecords being written as required). If necessary, implementors can explicitly start ContinueRecords (regardless of the amount of remaining space).

Parameters:

out - a data output stream

getNumberOfInfoRecsForStrings

public static int getNumberOfInfoRecsForStrings(int numStrings)

getRecordSizeForStrings

public static int getRecordSizeForStrings(int numStrings)

Given a number of strings (in the sst), returns the size of the extsst record

Parameters:

numStrings - the number of strings

Returns:

the size of the extsst record

getSid

public short getSid()

Description copied from class: Record

return the non static version of the id for this record.

Specified by:

getSid in class Record

Returns:

he id for this record

setBucketOffsets

public void setBucketOffsets(int[] bucketAbsoluteOffsets,
                             int[] bucketRelativeOffsets)
