Constructor Detail

RowRecordsAggregate

public RowRecordsAggregate()

Creates a new instance of ValueRecordsAggregate

Method Detail

insertRow

public void insertRow(RowRecord row)

removeRow

public void removeRow(RowRecord row)

getRow

public RowRecord getRow(int rownum)

getPhysicalNumberOfRows

public int getPhysicalNumberOfRows()

getFirstRowNum

The row blocks are goupings of rows that contain the DBCell record after them

getRowBlockSize

public int getRowBlockSize(int block)

getRowCountForBlock

public int getRowCountForBlock(int block)

Returns the number of physical rows within a block

getStartRowNumberForBlock

public int getStartRowNumberForBlock(int block)

getEndRowNumberForBlock

public int getEndRowNumberForBlock(int block)

Returns the physical row number of the end row in a block

serializeRowBlock

private int serializeRowBlock(int block,
                    int offset,
                    byte[] data)

Serializes a block of the rows

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

serialize

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

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 - offset to begin writing at

data - byte array containing instance data

Returns:

number of bytes written

fillFields

protected void fillFields(RecordInputStream in)

You never fill an aggregate

Specified by:

fillFields in class Record

Parameters:

in - the RecordInputstream to read the record from

validateSid

protected void validateSid(short id)

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

getSid

public short getSid()

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

Specified by:

getSid in class Record

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).

Overrides:

getRecordSize in class Record

getIterator

public Iterator getIterator()

clone

public Object clone()

Performs a deep clone of the record

Overrides:

clone in class Record
