Summary

class  FlowInitializer
     extends java.lang.Object
     implements java.lang.Runnable
{
          // Fields 3
     private String[] args;
     private CommSpaceHandle commSpaceHandle;
     private String startClass;

          // Constructors 1
     private FlowInitializer(String, String[], CommSpaceHandle);

          // Methods 5
     static FlowInitializer createInFlow(Flow, FlowStartSpec);
     private static FlowRun createStartClassInstance(Class) throws Error, NoSuchMethodException, IllegalAccessException, InstantiationException, InvocationTargetException;
     private static void initializeFlow(Flow);
     private static void startInitialClass(Flow, String, String[], CommSpaceHandle) throws ExceptionInInitializerError;

     public void run();
}

Callback for initializing a new Flow (in the context of one of its own threads).

This class's run() should be a method on a Flow object, but starting a thread requires a public run() method, which would be visible to the world on Flow.

XXX overlaps with the public FlowStartSpec?

   static FlowInitializer createInFlow(Flow flow, 
                                       FlowStartSpec fss) 

Create the a FlowInitializer in the heap of the given flow (i.e., not the current flow).

Returns:

a cross-heap pointer to a FlowInitializer

   public void run() 

Implements:

run in interface Runnable

   private static void initializeFlow(Flow flow) 

Initialize the flow object. Just creates the flow's class loader.

   private static void startInitialClass(Flow flow, 
                                         String startClass, 
                                         String[] args, 
                                         CommSpaceHandle csh)  throws ExceptionInInitializerError

Start the flow on its way.

   private static FlowRun createStartClassInstance(Class c)  throws Error, NoSuchMethodException, IllegalAccessException, InstantiationException, InvocationTargetException
