recordCheckpoint

public void recordCheckpoint()

Specified by:

recordCheckpoint in interface ValueOutputStream<DecimalStreamCheckpoint>

close

public void close()

Specified by:

close in interface ValueOutputStream<DecimalStreamCheckpoint>

getCheckpoints

public List<DecimalStreamCheckpoint> getCheckpoints()

Specified by:

getCheckpoints in interface ValueOutputStream<DecimalStreamCheckpoint>

getStreamDataOutput

public StreamDataOutput getStreamDataOutput(OrcColumnId columnId)

Specified by:

getStreamDataOutput in interface ValueOutputStream<DecimalStreamCheckpoint>

getBufferedBytes

public long getBufferedBytes()

Description copied from interface: ValueOutputStream

This method returns the size of the flushed data plus any unflushed data. If the output is compressed, flush data size is the size after compression.

Specified by:

getBufferedBytes in interface ValueOutputStream<DecimalStreamCheckpoint>

getRetainedBytes

public long getRetainedBytes()

Specified by:

getRetainedBytes in interface ValueOutputStream<DecimalStreamCheckpoint>

reset

public void reset()

Specified by:

reset in interface ValueOutputStream<DecimalStreamCheckpoint>
