Method Detail

launch

public Proc launch(Launcher.ProcStarter starter)
            throws IOException

Description copied from class: Launcher

Primarily invoked from Launcher.ProcStarter.start() to start a process with a specific launcher.

Specified by:

launch in class Launcher

Throws:

IOException

launchChannel

public hudson.remoting.Channel launchChannel(String[] cmd,
                                             OutputStream out,
                                             FilePath workDir,
                                             Map<String,String> envVars)
                                      throws IOException,
                                             InterruptedException

Description copied from class: Launcher

Launches a specified process and connects its input/output to a Channel, then return it.

When the returned channel is terminated, the process will be killed.

Specified by:

launchChannel in class Launcher

out - Where the stderr from the launched process will be sent.

workDir - The working directory of the new process, or null to inherit from the current process

envVars - Environment variable overrides. In addition to what the current process is inherited (if this is going to be launched from a slave agent, that becomes the "current" process), these variables will be also set.

Throws:

IOException

InterruptedException

kill

public void kill(Map<String,String> modelEnvVars)
          throws IOException,
                 InterruptedException

Description copied from class: Launcher

Calls ProcessTree.killAll(Map) to kill processes.

Specified by:

kill in class Launcher

Throws:

IOException

InterruptedException

isUnix

public boolean isUnix()

Description copied from class: Launcher

Returns true if this Launcher is going to launch on Unix.

Overrides:

isUnix in class Launcher

launch

public Proc launch(String[] cmd,
                   boolean[] mask,
                   String[] env,
                   InputStream in,
                   OutputStream out,
                   FilePath workDir)
            throws IOException

Description copied from class: Launcher

Launch a command with optional censoring of arguments from the listener (Note: The censored portions will remain visible through /proc, pargs, process explorer, etc. i.e. people logged in on the same machine This version of the launch command just ensures that it is not visible from a build log which is exposed via the web)

Overrides:

launch in class Launcher

Parameters:

cmd - The command and all it's arguments.

mask - Which of the command and arguments should be masked from the listener

env - Environment variable overrides.

in - null if there's no input.

out - stdout and stderr of the process will be sent to this stream. the stream won't be closed.

workDir - null if the working directory could be anything.

Returns:

The process of the command.

Throws:

IOException - When there are IO problems.

getComputer

public Computer getComputer()

Description copied from class: Launcher

If this Launcher is encapsulating an execution on a specific Computer, return it.

Because of the way internal Hudson abstractions are set up (that is, Launcher only needs a VirtualChannel to do its job and isn't really required that the channel comes from an existing Computer), this method may not always the right Computer instance.

Overrides:

getComputer in class Launcher

Returns:

null if this launcher is not created from a Computer object.

getListener

public TaskListener getListener()

Description copied from class: Launcher

Gets the TaskListener that this launcher uses to report the commands that it's executing.

Overrides:

getListener in class Launcher

toString

public String toString()

Overrides:

toString in class Object

getChannel

public hudson.remoting.VirtualChannel getChannel()

Description copied from class: Launcher

Gets the channel that can be used to run a program remotely.

Overrides:

getChannel in class Launcher

Returns:

null if the target node is not configured to support this. this is a transitional measure. Note that a launcher for the master is always non-null.

launch

public Proc launch(String[] cmd,
                   String[] env,
                   InputStream in,
                   OutputStream out,
                   FilePath workDir)
            throws IOException

Overrides:

launch in class Launcher

env - Environment variable overrides.

in - null if there's no input.

out - stdout and stderr of the process will be sent to this stream. the stream won't be closed.

workDir - null if the working directory could be anything.

Throws:

IOException

getInner

public Launcher getInner()

Gets nested launcher.

Returns:

Inner launcher
