15. Basic Concept of Symbian C++ • Stack and Heap • Leaves • Two Phase construction • Active Object Context-Aware Group, Intelligent Agents Lab

16. Stack and Heap • Stack • Object are delete automatically • Default size is 8kb • Heap • Object must deleted by programmer using delete • Example Context-Aware Group, Intelligent Agents Lab

17. Leaves • Leaves are used instead of C++ exception • When there is a resource failure, the code “leave” • The new operator has been overload to leave if insufficient memory is available • Use new (ELeave) • Functions that can leave should end in “L” Context-Aware Group, Intelligent Agents Lab

18. Two Phase Construction • C++ constructor must never leave as the destructor will not be called Context-Aware Group, Intelligent Agents Lab

19. Active Object • Events are scheduled by the active scheduler • Events are handled by active object • Each application has an active scheduler • The active scheduler runs in a loop in the application’s main loop • Active objects have a: • TRequestStatus bas class member, iStatus, that is passed inro asynchronous functions • RunL() Function that is called when the action completes • DoCancel() function that is called when the action is cancelled Context-Aware Group, Intelligent Agents Lab
