Method Details

format

public String format()

Specified by:

format in interface BlockEncoder

add

public void add(int blockId,
long recordId,
SnapshotEntry entry,
int[] valueBlockIds,
int[] valueIndexes)

Specified by:

add in interface LeafBlockEncoder

numRecords

public int numRecords()

Description copied from interface: DataBlockEncoder

The number of items in the block. Zero indicates we don't need to flush it.

Specified by:

numRecords in interface DataBlockEncoder

numBytes

public int numBytes()

Description copied from interface: DataBlockEncoder

Used to determine when to flush a block. We won't always know the exact block size until we actually encode it.

Specified by:

numBytes in interface DataBlockEncoder

firstKey

public byte[] firstKey()

Specified by:

firstKey in interface LeafBlockEncoder

assertKeysSorted

public void assertKeysSorted()

Specified by:

assertKeysSorted in interface LeafBlockEncoder

blockId

public int blockId()

Specified by:

blockId in interface LeafBlockEncoder

firstValueBlockId

public int firstValueBlockId(int column)

Specified by:

firstValueBlockId in interface LeafBlockEncoder

numValueBlocks

public int numValueBlocks(int column)

Specified by:

numValueBlocks in interface LeafBlockEncoder

encode

public EncodedBlock encode(BlockQueue.FileIdsAndEndings[] fileIdsAndEndings)

Specified by:
