Class BlockingWritableByteChannel

java.lang.Object
  org.jboss.xnio.channels.BlockingWritableByteChannel

All Implemented Interfaces:

Closeable, Flushable, Channel, GatheringByteChannel, WritableByteChannel

public class BlockingWritableByteChannel
extends Object
implements GatheringByteChannel, Flushable

A blocking wrapper for a StreamChannel. Write operations will block until some data may be transferred. Once any amount of data is written, the operation will return.

Constructor Summary

BlockingWritableByteChannel(StreamSinkChannel delegate)
Construct a new instance.

BlockingWritableByteChannel(StreamSinkChannel delegate, long writeTimeout, TimeUnit writeTimeoutUnit)
Construct a new instance.

Method Summary

void	close()
void	flush()
boolean	isOpen()
void	setWriteTimeout(long writeTimeout, TimeUnit writeTimeoutUnit) Set the write timeout.
int	write(ByteBuffer src) Perform a blocking write operation.
long	write(ByteBuffer[] srcs) Perform a blocking, gathering write operation.
long	write(ByteBuffer[] srcs, int offset, int length) Perform a blocking, gathering write operation.
