public interface Channel
extends Closeable, SSHPacketHandler, ErrorNotifiable

A channel is the basic medium for application-layer data on top of an SSH transport.

Nested Class Summary

static interface	Channel.Direct Direct channels are those that are initiated by us.
static interface	Channel.Forwarded Forwarded channels are those that are initiated by the server.

Method Detail

close

void close()
           throws TransportException,
                  ConnectionException

Close this channel.

Specified by:

close in interface Closeable

Throws:

TransportException

ConnectionException

getAutoExpand

boolean getAutoExpand()

Returns:

whether auto-expansion of local window is set.

See Also:

setAutoExpand(boolean)

getID

int getID()

Returns:

the channel ID

getInputStream

InputStream getInputStream()

Returns:

the InputStream for this channel.

getLocalMaxPacketSize

int getLocalMaxPacketSize()

Returns:

the maximum packet size that we have specified.

getLocalWinSize

int getLocalWinSize()

Returns:

the current local window size.

getOutputStream

OutputStream getOutputStream()

Returns:

an OutputStream for this channel.

getRecipient

int getRecipient()

Returns:

the channel ID at the remote end.

getRemoteMaxPacketSize

int getRemoteMaxPacketSize()

Returns:

the maximum packet size as specified by the remote end.

getRemoteWinSize

int getRemoteWinSize()

Returns:

the current remote window size.

getType

String getType()

Returns:

the channel type identifier.

isOpen

boolean isOpen()

Returns:

whether the channel is open.

sendEOF

void sendEOF()
             throws TransportException

Sends an EOF message to the server for this channel; indicating that no more data will be sent by us. The OutputStream for this channel will be closed and no longer usable.

Throws:

TransportException - if there is an error sending the EOF message

setAutoExpand

void setAutoExpand(boolean autoExpand)

Set whether local window should automatically expand when data is received, irrespective of whether data has been read from that stream. This is useful e.g. when a remote command produces a lot of output that would fill the local window but you are not interested in reading from its InputStream.

Parameters:

autoExpand - whether local windows should automatically expand

join

void join()
          throws ConnectionException

Throws:

ConnectionException

join

void join(int timeout,
          TimeUnit unit)
          throws ConnectionException

Throws:

ConnectionException
