Constructor Detail

ValueRecordsAggregate

public ValueRecordsAggregate()

Creates a new instance of ValueRecordsAggregate

Method Detail

insertCell

public void insertCell(CellValueRecordInterface cell)

removeCell

public void removeCell(CellValueRecordInterface cell)

getPhysicalNumberOfCells

public int getPhysicalNumberOfCells()

getFirstCellNum

public int getFirstCellNum()

getLastCellNum

public int getLastCellNum()

construct

public int construct(int offset,
            List records)

serialize

public 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.

Specified by:

serialize in class Record

Parameters:

offset - to begin writing at

data - byte array containing instance data

Returns:

number of bytes written

getRowCellBlockSize

public int getRowCellBlockSize(int startRow,
                      int endRow)

Tallies a count of the size of the cell records that are attached to the rows in the range specified.

rowHasCells

public boolean rowHasCells(int row)

Returns true if the row has cells attached to it

serializeCellRow

public int serializeCellRow(int row,
                   int offset,
                   byte[] data)

Serializes the cells that are allocated to a certain row range

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
