java.lang.Object java.io.OutputStream org.apache.hadoop.net.SocketOutputStream
public class SocketOutputStream
This implements an output stream that can have a timeout while writing.
This sets non-blocking flag on the socket channel.
So after creating this object , read() on
Socket.getInputStream()
and write() on
Socket.getOutputStream()
on the associated socket will throw
llegalBlockingModeException.
Please use SocketInputStream
for reading.
Constructor Summary | |
---|---|
SocketOutputStream(Socket socket,
long timeout)
Same as SocketOutputStream(socket.getChannel(), timeout): Create a new ouput stream with the given timeout. |
|
SocketOutputStream(WritableByteChannel channel,
long timeout)
Create a new ouput stream with the given timeout. |
Method Summary | |
---|---|
void |
close()
|
WritableByteChannel |
getChannel()
Returns underlying channel used by this stream. |
boolean |
isOpen()
|
void |
transferToFully(FileChannel fileCh,
long position,
int count)
Transfers data from FileChannel using FileChannel.transferTo(long, long, WritableByteChannel) . |
void |
waitForWritable()
waits for the underlying channel to be ready for writing. |
void |
write(byte[] b,
int off,
int len)
|

public SocketOutputStream(WritableByteChannel channel, long timeout) throws IOException
channel
- Channel for writing, should also be a SelectableChannel
.
The channel will be configured to be non-blocking.timeout
- timeout in milliseconds. must not be negative.
IOException
public SocketOutputStream(Socket socket, long timeout) throws IOException
socket
- should have a channel associated with it.timeout
- timeout timeout in milliseconds. must not be negative.

SocketTimeoutException
- if select on the channel times out.
IOException
- if any other I/O error occurs.public void transferToFully(FileChannel fileCh, long position, int count) throws IOException
FileChannel.transferTo(long, long, WritableByteChannel)
.
Similar to readFully(), this waits till requested amount of
data is transfered.
fileCh
- FileChannel to transfer data from.position
- position within the channel where the transfer beginscount
- number of bytes to transfer.
EOFException
- If end of input file is reached before requested number of
bytes are transfered.
SocketTimeoutException
- If this channel blocks transfer longer than timeout for
this stream.
IOException
- Includes any exception thrown by
FileChannel.transferTo(long, long, WritableByteChannel)
.
