All Implemented Interfaces:

Closeable, Flushable

public class ChannelOutputStream
extends OutputStream

An output stream which writes to a stream sink channel. All write operations are directly performed upon the channel, so for optimal performance, a buffering output stream should be used to wrap this class.

Since:

1.2

Field Summary

protected StreamSinkChannel	channel
protected boolean	closed
protected long	timeout

Constructor Summary

ChannelOutputStream(StreamSinkChannel channel)
Construct a new instance.

ChannelOutputStream(StreamSinkChannel channel, long timeout, TimeUnit unit)
Construct a new instance.

Method Summary

void	close()
void	flush()
long	getWriteTimeout(TimeUnit unit) Get the write timeout.
void	setWriteTimeout(long timeout, TimeUnit unit) Set the write timeout.
void	write(byte[] b)
void	write(byte[] b, int off, int len)
