Stopping an IVoiceXMLBrowser implementation [message #12465]

Hi,

What is the correct way to code the IVoiceXMLBrowser.stop() method? I
have stored a reference to the VoiceXMLBrowserProcess supplied by
setProcess but I am seeing a stack overflow when I try to terminate the
process.

The following implementation:

int count = 0;

public void stop() {
if (count++ >= 10) {
return;
}

System.out.println("MyBrowser stop. Can terminate? "
+ process.canTerminate() + ", isTerminated? "
+ process.isTerminated());
try {
process.terminate();
process.setTerminated(true);
} catch (DebugException e) {
System.out.println("DebugException: " + e.getMessage());
}
System.out.println("After terminate. Can terminate? "
+ process.canTerminate() + ", isTerminated? "
+ process.isTerminated());
}

produces this output:

MyBrowser stop. Can terminate? true, isTerminated? false
MyBrowser stop. Can terminate? true, isTerminated? false
MyBrowser stop. Can terminate? true, isTerminated? false
MyBrowser stop. Can terminate? true, isTerminated? false
MyBrowser stop. Can terminate? true, isTerminated? false
MyBrowser stop. Can terminate? true, isTerminated? false
MyBrowser stop. Can terminate? true, isTerminated? false
MyBrowser stop. Can terminate? true, isTerminated? false
MyBrowser stop. Can terminate? true, isTerminated? false
MyBrowser stop. Can terminate? true, isTerminated? false
After terminate. Can terminate? false, isTerminated? true
After terminate. Can terminate? false, isTerminated? true
After terminate. Can terminate? false, isTerminated? true
After terminate. Can terminate? false, isTerminated? true
After terminate. Can terminate? false, isTerminated? true
After terminate. Can terminate? false, isTerminated? true
After terminate. Can terminate? false, isTerminated? true
After terminate. Can terminate? false, isTerminated? true
After terminate. Can terminate? false, isTerminated? true
After terminate. Can terminate? false, isTerminated? true

I tried swapping the the process.terminate(); and
process.setTerminated(true); statements but this resulted in the browser
failing to terminate, that is to say the Terminate button remained red
and the DTMF buttons were still active, but I didn't get a stack overflow.

Any advice greatly appreciated.

Regards,

Marcus.

The best example is the Tellme implementation in here:

http://dev.eclipse.org/viewcvs/indextech.cgi/org.eclipse.vtp /simdebug/plugins/org.eclipse.vtp.launching.tellme/src/org/e clipse/vtp/launching/internal/tellme/

In particular CallState.endLaunch() does this:

(activeBrowser is a VoiceXMLBrowserProcess object)

activeBrowser.setTerminated(true);
DebugEvent[] event = new DebugEvent[2];
event[0] = new DebugEvent(activeBrowser, DebugEvent.TERMINATE);
event[1] = new DebugEvent(activeBrowser.getLaunch(), DebugEvent.CHANGE);
DebugPlugin.getDefault().fireDebugEventSet(event);

What you're doing is communicating to both the process object and to the
eclipse infrastructure that you've now terminated. The first step is to
change the isTerminated() bit in the process object using setTerminated()
and the events tell the UI and any listeners that the session is now over.
The UI responds to those events by checking isTerminated() in the process
object to refresh its tree of items in the Debug perspective's debug view.

The VoiceXMLBrowserProcess.terminate() method in the process object actually
attempts to shutdown the process itself by calling the stop() method, so
calling it will get you in a loop there. It's there to be called by the UI
if the user pressed the terminate button in the Debug perspective's debug
view while they have selected the process object.

Hope that helps.

Great to hear! If you have a chance we'd love feedback on what was hard/easy
to get working..besides the stopping issue I suppose :).
