Class FastOutputStream

java.lang.Object
  java.io.OutputStream
      org.apache.solr.common.util.FastOutputStream

All Implemented Interfaces:

Closeable, DataOutput, Flushable

public class FastOutputStream
extends OutputStream
implements DataOutput

Single threaded buffered OutputStream Internal Solr use only, subject to change.

Field Summary

protected byte[]	buf
protected OutputStream	out
protected int	pos
protected long	written

Constructor Summary

FastOutputStream(OutputStream w)

FastOutputStream(OutputStream sink, byte[] tempBuffer, int start)

Method Summary

void	close()
void	flush()
void	flush(byte[] buf, int offset, int len) All writes to the sink will go through this method
void	flushBuffer() Only flushes the buffer of the FastOutputStream, not that of the underlying stream.
void	reserve(int len) reserve at least len bytes at the end of the buffer.
void	setWritten(long written) Resets the count returned by written()
long	size()
static FastOutputStream	wrap(OutputStream sink)
void	write(byte b)
void	write(byte[] b)
void	write(byte[] arr, int off, int len)
void	write(int b)
void	writeBoolean(boolean v)
void	writeByte(int v)
void	writeBytes(String s)
void	writeChar(int v)
void	writeChars(String s)
void	writeDouble(double v)
void	writeFloat(float v)
void	writeInt(int v)
void	writeLong(long v)
void	writeShort(int v)
void	writeUTF(String s)
long	written() Returns the number of bytes actually written to the underlying OutputStream, not including anything currently buffered by this class itself.
