Detailed Description

The abstract base class for the different types of channel which may be associated with a Session.

It should be considered an implementation detail that Channel implements Runnable – external code never has to invoke the run method.

void com.jcraft.jsch.Channel.connect (  )  throws JSchException

Opens the channel without any timeout.

This is equivalent to connect(0) if not overridden in subclasses.

Reimplemented in com.jcraft.jsch.ChannelDirectTCPIP.

static Channel com.jcraft.jsch.Channel.getChannel ( int  id,
Session  session 
) [static, package]

Retrieves a channel from the channel pool.

Parameters:
id the session-specific identifier of the channel
session the session with which the channel is associated.
