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:

getRetainedBytes

public long getRetainedBytes()

Specified by:

getRetainedBytes in interface ValueOutputStream<DecimalStreamCheckpoint>

reset

public void reset()

Specified by:

reset in interface ValueOutputStream<DecimalStreamCheckpoint>
