DeltaRecord

public DeltaRecord()

DeltaRecord

public DeltaRecord(RecordInputStream in)

Constructs a Delta record and sets its fields appropriately.

Parameters:

in - the RecordInputstream to read the record from

Method Detail

validateSid

protected void validateSid(short id)

Description copied from class: Record

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

Specified by:

validateSid in class Record

Parameters:

id - alleged id for this record

fillFields

protected void fillFields(RecordInputStream in)

Description copied from class: Record

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

Specified by:

fillFields in class Record

Parameters:

in - the RecordInputstream to read the record from

setMaxChange

public void setMaxChange(double maxChange)

set the maximum change

Parameters:

maxChange - - maximum rounding error

getMaxChange

public double getMaxChange()

get the maximum change

Returns:

maxChange - maximum rounding error

toString

public java.lang.String toString()

Description copied from class: Record

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

Overrides:

toString in class Record

serialize

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

Description copied from class: Record

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.

Specified by:

serialize in class Record

Parameters:

offset - to begin writing at

data - byte array containing instance data

Returns:

number of bytes written

getRecordSize

public int getRecordSize()

Description copied from class: Record

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

getRecordSize in class 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

clone
