public abstract class WritableRecordData

extends RecordData

implements ByteData

Extension of the standard RecordData which is used to support those records which, once read, may also be written

Field Summary

protected static int

maxRecordLength The maximum length allowed by Excel for any record length

Fields inherited from class jxl.biff.RecordData

code, record

Constructor Summary

protected	WritableRecordData(Record t) Constructor used when reading a record
protected	WritableRecordData(Type t) Constructor used by the writable records

Method Summary

byte[]	getBytes() Used when writing out records.
protected abstract byte[]	getData() Abstract method called by the getBytes method.
private byte[]	handleContinueRecords(byte[] data) The number of bytes for this record exceeds the maximum record length, so a continue is required

Field Detail

maxRecordLength

protected static final int maxRecordLength

The maximum length allowed by Excel for any record length

Constructor Detail

WritableRecordData

protected WritableRecordData(Type t)

Constructor used by the writable records

Parameters:

t - the biff type of this record

WritableRecordData

protected WritableRecordData(Record t)

Constructor used when reading a record

Parameters:

t - the raw data read from the biff file

Method Detail

getBytes

public final byte[] getBytes()

Used when writing out records. This portion of the method handles the biff code and the length of the record and appends on the data retrieved from the subclasses

Specified by:

getBytes in interface ByteData

Returns:

the full record data to be written out to the compound file

handleContinueRecords

private byte[] handleContinueRecords(byte[] data)

The number of bytes for this record exceeds the maximum record length, so a continue is required

getData

protected abstract byte[] getData()

Abstract method called by the getBytes method. Subclasses implement this method to incorporate their specific binary data - excluding the biff code and record length, which is handled by this class

Returns:

subclass specific biff data
