      org.jboss.xnio.channels.ChannelInputStream

All Implemented Interfaces:

Closeable

public class ChannelInputStream
extends InputStream

An input stream which reads from a stream source channel. All read operations are directly performed upon the channel, so for optimal performance, a buffering input stream should be used to wrap this class.

Since:

1.2

Field Summary

protected StreamSourceChannel	channel
protected boolean	closed
protected long	timeout

Constructor Summary

ChannelInputStream(StreamSourceChannel channel)
Construct a new instance.

ChannelInputStream(StreamSourceChannel channel, long timeout, TimeUnit timeoutUnit)
Construct a new instance.

Method Summary

void	close()
long	getReadTimeout(TimeUnit unit) Get the read timeout.
int	read()
int	read(byte[] b)
int	read(byte[] b, int off, int len)
void	setReadTimeout(long timeout, TimeUnit unit) Set the read timeout.
