Class ByteArrayOutputStream

java.lang.Object

com.facebook.presto.orc.stream.ByteArrayOutputStream

All Implemented Interfaces:

ValueOutputStream<ByteArrayStreamCheckpoint>

public class ByteArrayOutputStream
extends Object
implements ValueOutputStream<ByteArrayStreamCheckpoint>

This is a concatenation of all byte array content, and a separate length stream will be used to get the boundaries.

close

public void close()

Specified by:

close in interface ValueOutputStream<ByteArrayStreamCheckpoint>

recordCheckpoint

public void recordCheckpoint()

Specified by:

recordCheckpoint in interface ValueOutputStream<ByteArrayStreamCheckpoint>

getCheckpoints

public List<ByteArrayStreamCheckpoint> getCheckpoints()

Specified by:

getCheckpoints in interface ValueOutputStream<ByteArrayStreamCheckpoint>

getStreamDataOutput

public StreamDataOutput getStreamDataOutput(int column)

Specified by:

getStreamDataOutput in interface ValueOutputStream<ByteArrayStreamCheckpoint>

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<ByteArrayStreamCheckpoint>

getRetainedBytes

public long getRetainedBytes()

Specified by:

getRetainedBytes in interface ValueOutputStream<ByteArrayStreamCheckpoint>

reset

public void reset()

Specified by:

reset in interface ValueOutputStream<ByteArrayStreamCheckpoint>
