Constructor Detail

IndexRecord

public IndexRecord(int pos,
                   int r,
                   int bl)

Constructor

Parameters:

pos - the position of the BOF record

bl - the number of blocks

r - the number of rows

Method Detail

getData

protected byte[] getData()

Gets the binary data for output. This writes out an empty data block, and the information is filled in later on when the information becomes available

Overrides:

getData in class WritableRecordData

Returns:

the binary data

addBlockPosition

void addBlockPosition(int pos)

Adds another index record into the array

Parameters:

pos - the position in the output file

setDataStartPosition

void setDataStartPosition(int pos)

Sets the position of the data start. This happens to be the position of the DEFCOLWIDTH record
