public abstract class Record
extends Object

Title: Record Description: All HSSF Records inherit from this class. It populates the fields common to all records (id, size and data). Subclasses should be sure to validate the id, Company:

Methods

Modifier and Type	Method and Description
Object	clone()
protected abstract void	fillFields(RecordInputStream in) called by the constructor, should set class level fields.
int	getRecordSize() gives the current serialized size of the record.
abstract short	getSid() return the non static version of the id for this record.
boolean	isInValueSection() DBCELL, ROW, VALUES all say yes
boolean	isValue() tells whether this type of record contains a value
byte[]	serialize() called by the class that is responsible for writing this sucker.
abstract int	serialize(int offset, byte[] data) called by the class that is responsible for writing this sucker.
String	toString() get a string representation of the record (for biffview/debugging)

Constructor Detail

Record

public Record()

instantiates a blank record strictly for ID matching

Record

public Record(RecordInputStream in)

Constructor Record

Parameters:

in - the RecordInputstream to read the record from

Method Detail

validateSid

protected abstract void validateSid(short id)

called by constructor, should throw runtime exception in the event of a record passed with a differing ID.

Parameters:

id - alleged id for this record

fillFields

protected abstract void fillFields(RecordInputStream in)

called by the constructor, should set class level fields. Should throw runtime exception for bad/icomplete data.

Parameters:

in - the RecordInputstream to read the record from

serialize

public byte[] serialize()

called by the class that is responsible for writing this sucker. Subclasses should implement this so that their data is passed back in a byte array.

Returns:

byte array containing instance data

serialize

public abstract int serialize(int offset,
            byte[] data)

called by the class that is responsible for writing this sucker. Subclasses should implement this so that their data is passed back in a byte array.

Parameters:

offset - to begin writing at

data - byte array containing instance data

Returns:

number of bytes written

getRecordSize

public int getRecordSize()

gives the current serialized size of the record. Should include the sid and reclength (4 bytes).

isValue

public boolean isValue()

tells whether this type of record contains a value

isInValueSection

public boolean isInValueSection()

DBCELL, ROW, VALUES all say yes

toString

public String toString()

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

Overrides:

toString in class Object

getSid

public abstract short getSid()

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

clone

public Object clone()

Overrides:

clone in class Object
