public interface WritableByteChannel extends Channel
WritableByteChannelis a type of
Channelthat can write bytes.
Write operations are synchronous on a
WritableByteChannel, that is,
if a write is already in progress on the channel then subsequent writes will
block until the first write completes. It is undefined whether non-write
operations will block.
int write(ByteBuffer buffer) throws IOException
The maximum number of bytes that will be written is the
remaining() number of bytes in the buffer when the method
invoked. The bytes will be written from the buffer starting at the
The call may block if other threads are also attempting to write on the same channel.
Upon completion, the buffer's
position() is updated to the
end of the bytes that were written. The buffer's
buffer- the byte buffer containing the bytes to be written.
NonWritableChannelException- if the channel was not opened for writing.
ClosedChannelException- if the channel was already closed.
AsynchronousCloseException- if another thread closes the channel during the write.
ClosedByInterruptException- if another thread interrupt the calling thread during the write.
IOException- another IO exception occurs, details are in the message.
