1.38 +/**
1.39 +An generic active object that can be used to wait for an iStatus to be signalled.
1.40 +This has a similar effect to User::WaitForRequest(), but works without
1.41 +blocking the thread (which allows other active objects within the thread
1.42 +to continue). Instead, a nested active scheduler loop is used.
1.43 +
1.44 +To use a CActiveWaiter, pass its iStatus to an asynchronous method, as usual.
1.45 +Then call WaitActiveL() instead of SetActive().
1.46 +
1.47 +The call will block until the asynchronous completes.
1.48 +
1.49 +E.g.
1.50 +
1.51 +void CMyClass::Foo()
1.52 +{
1.53 + CActiveWaiter* waiter = new(ELeave)CActiveWaiter;
1.54 +
1.55 + iAsyncObj->Bar(waiter->iStatus);
1.56 + waiter->WaitActiveL();
1.57 +
1.58 + delete waiter;
1.59 +}
