Examples of org.openbp.server.context.CallStackItem

org.openbp.server.context.CallStackItem
Item that has been pushed onto the call stack. Please note that the NodeSocket held by the class maybe an exit or an entry socket, depending on whether a subprocess or something different is described by the StackItem.
The item also holds the current position before the call. @author Heiko Erhardt

    List elements = new ArrayList();


    // Iterate the call stack and create the list of stack info objects
    for (Iterator it = callStack.iterator(); it.hasNext();)
    {
      CallStackItem stackItem = (CallStackItem) it.next();


      CallStackInfo stackInfo = new CallStackInfo();


      stackInfo.setType(stackItem.getType());


      // TODO Fix 5 No difference between current pos. and saved pos. of call stack info
      NodeSocket nodeSocket = stackItem.getNodeSocket();
      stackInfo.setCurrentPosition(nodeSocket.getQualifier());
      stackInfo.setSavedPosition(nodeSocket.getQualifier());


      elements.add(stackInfo);
    }
