示例1: findActivity

/**
 * Get a root activity for a new interpreter instance.
 *
 * @return The newly created activity.
 */
Activity *ActivityManager::getRootActivity()
{
    // it's possible we already have an activity active for this thread.  That
    // most likely occurs in nested RexxStart() calls.  Get that activity first,
    // and if we have one, we'll need to push this down.
    Activity *oldActivity = findActivity();

    // we need to lock the kernel to have access to the memory manager to
    // create this activity.
    lockKernel();

    // get a new activity object
    Activity *activityObject = createCurrentActivity();
    unlockKernel();
    // mark this as the root activity for an interpreter instance.  Some operations
    // are only permitted from the root threads.
    activityObject->setInterpreterRoot();

    // Do we have a nested interpreter call occurring on the same thread?  We need to
    // mark the old activity as suspended, and chain this to the new activity.
    if (oldActivity != OREF_NULL)
    {
        oldActivity->setSuspended(true);
        // this pushes this down the stack.
        activityObject->setNestedActivity(oldActivity);
    }

    // now we need to have this activity become the kernel owner.
    activityObject->requestAccess();
    // this will help ensure that the code after the request access call
    // is only executed after access acquired.
    sentinel = true;

    activityObject->activate();        // let the activity know it's in use, potentially nested
    // belt-and-braces.  Make sure the current activity is explicitly set to
    // this activity before leaving.
    currentActivity = activityObject;
    return activityObject;
