Method Detail

nextActionId

protected static int nextActionId()

runActionThread

protected static void runActionThread(int actionId,
                                      String act,
                                      Runnable action,
                                      String name,
                                      boolean synchronous)

Creates and runs a dynamic action thread to carry out the action on behalf of the client. This allows clients invoking asynchronous versions of the action to immediately get back to work. The thread handles any exceptions that occur during the action. If the action is synchronous, this method does not return until the dynamic action thread completes.

notifyDynamicActionComplete

protected static void notifyDynamicActionComplete(int actionId)

Used by master to notify the client that the action is complete. Only invoked for synchronous actions. Goes through a client intermediary.
