abbot.script
Class ForkedStepRunner  

java.lang.Object
  abbot.script.StepRunner
      abbot.script.ForkedStepRunner

All Implemented Interfaces:

abbot.i18n.Resources, abbot.editor.i18n.Resources

---

public class ForkedStepRunner

extends StepRunner

A StepRunner that runs the step in a separate VM. Behavior should be indistinguishable from the base StepRunner.

---

Nested Class Summary
(package private)  class	ForkedStepRunner.ForkedError           An exception that for all purposes looks like another exception.
(package private)  class	ForkedStepRunner.ForkedFailure           An exception that for all purposes looks like another exception.
protected static class	ForkedStepRunner.SlaveProcess           When actually within the separate VM, this is what gets run.

Method Detail

fork

java.lang.Process fork(java.lang.String vmargs,
                       java.lang.String[] cmdArgs)
                 throws java.io.IOException

---

fork

java.lang.Process fork(java.lang.String vmargs)
                 throws java.net.UnknownHostException,
                        java.io.IOException

Launch a new process, using this class as the main class.

---

runStep

public void runStep(Step step)

Running the step in a separate VM should be indistinguishable from running a regular script. When running as master, nothing actually runs locally. We just fork a subprocess and run the script in that, reporting back its progress as if it were running locally.

Overrides:

runStep in class StepRunner

---

forkProcess

private java.lang.Process forkProcess(java.lang.String vmargs)
                               throws java.lang.Throwable

---

sendScript

private void sendScript(Script script)
                 throws java.io.IOException

---

trackScript

private void trackScript(Script script)
                  throws java.io.IOException

---

decodeStep

static Step decodeStep(Sequence root,
                       java.lang.String code)

---

encodeStep

static java.lang.String encodeStep(Sequence root,
                                   Step step)

Encode the given step into a set of indices.

---

receiveEvent

private StepEvent receiveEvent(Script script)
                        throws java.io.IOException

Receive a serialized event on the connection and convert it back into a real event, setting the given step's exception/error if necessary.

---

writeMessage

private static void writeMessage(java.net.Socket connection,
                                 java.lang.String msg)
                          throws java.io.IOException

---

readMessage

private static java.lang.String readMessage(java.net.Socket connection)
                                     throws java.io.IOException

---

main

public static void main(java.lang.String[] args)

Provide means to control execution and feedback of a script in a separate process.
