All Implemented Interfaces:

Closeable, Flushable

public class ByteBufferOutputStream
extends OutputStream

Utility to collect data written to an OutputStream in ByteBuffers. Originally from org.apache.avro.util.ByteBufferOutputStream, moved into Hector and added getByteBuffer to return single ByteBuffer from contents.

Constructor Summary

ByteBufferOutputStream()

Method Summary

void	append(List<ByteBuffer> lists) Append a list of ByteBuffers to this stream.
List<ByteBuffer>	getBufferList() Returns all data written and resets the stream to be empty.
ByteBuffer	getByteBuffer()
void	prepend(List<ByteBuffer> lists) Prepend a list of ByteBuffers to this stream.
void	reset()
void	write(byte[] b)
void	write(byte[] b, int off, int len)
void	write(ByteBuffer buffer) Add a buffer to the output without copying, if possible.
void	write(int b)
void	writeChar(char value)
void	writeDouble(double value)
void	writeFloat(float value)
void	writeInt(int value)
void	writeLong(long value)
