Method Detail

visit

boolean visit(ApplicationMethods app,
              G9DialogController gdc)

Visit one dialog.

Parameters:

app - Current application

gdc - Dialog to visit

Returns:

The value returned must be specified by each individual visitor implementation. Typically, a G9BaseException will be thrown to abort the loop.

done

void done()

Callback when all dialogs are visited.

If you need to synchronously wait for a visitor running in a different thread, invoke the visit loop like this:

    DialogVisitor myVisitor= ...
    synchronized (myVisitor) {
        app.visitAll(myVisitor); // Maybe on another thread
        myVisitor.wait();
    } // Exception handling ommitted
    moreStuff...
 

and implement the done() method simply as follows:

    public synchronized void done() {
      notifyAll();
    }
