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

17. Context-Aware Group, Intelligent Agents Lab
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”

18. Two Phase Construction
C++ constructor must never leave as the destructor will not be called

19. Context-Aware Group, Intelligent Agents Lab
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
