Field Detail

tunnel

public final String tunnel

If the slave needs to tunnel the connection to the master, specify the "host:port" here. This can include the special syntax "host:" and ":port" to indicate the default host/port shall be used.

Null if no tunneling is necessary.

Method Detail

isLaunchSupported

public boolean isLaunchSupported()

Description copied from class: ComputerLauncher

Returns true if this ComputerLauncher supports programatic launch of the slave agent in the target Computer.

Overrides:

isLaunchSupported in class ComputerLauncher

launch

public void launch(SlaveComputer computer,
                   TaskListener listener)

Description copied from class: ComputerLauncher

Launches the slave agent for the given Computer.

If the slave agent is launched successfully, SlaveComputer.setChannel(InputStream, OutputStream, TaskListener, Channel.Listener) should be invoked in the end to notify Hudson of the established connection. The operation could also fail, in which case there's no need to make any callback notification, (except to notify the user of the failure through StreamTaskListener.) Also note that the normal return of this method call does not necessarily signify a successful launch. If someone programmatically calls this method and wants to find out if the launch was a success, use Computer.isOnline() at the end.

This method must operate synchronously. Asynchrony is provided by Computer.connect(boolean) and its correct operation depends on this.

Overrides:

launch in class ComputerLauncher

listener - The progress of the launch, as well as any error, should be sent to this listener.
