Method Detail

launchProcess

public void launchProcess(java.io.File jobDirectory,
                          java.io.File jobScript,
                          boolean interactive,
                          @Nullable
                          java.lang.Integer timeout,
                          boolean launchInJobDirectory)
                   throws JobLaunchException

Launch the job process (unless launch was aborted by previous a kill call).

Specified by:

launchProcess in interface JobProcessManager

Parameters:

jobDirectory - Job directory

jobScript - job script (a.k.a. run file)

interactive - launch in interactive mode (inherit I/O) or batch (no input, write outputs to files)

timeout - The optional number of seconds this job is allowed to run before the system will kill it

launchInJobDirectory - launch the job process from the job directory rather than the current directory

Throws:

JobLaunchException - if the job process failed to launch

kill

public void kill(KillService.KillSource source)

Terminate job process execution (if still running) or prevent it from launching (if not launched yet). Optionally sends SIGINT to the process (unnecessary under certain circumstances. For example, CTRL-C in a terminal session, is already received by the job process, issuing a second one is unneeded).

Specified by:

kill in interface JobProcessManager

Parameters:

source - The KillService.KillSource value representing where this kill request is coming from

waitFor

public JobProcessResult waitFor()
                         throws java.lang.InterruptedException

Wait indefinitely for the job process to terminate.

Specified by:

waitFor in interface JobProcessManager

Returns:

KILLED, SUCCESSFUL, or FAILED

Throws:

java.lang.InterruptedException - if the calling thread is interrupted while waiting
