Detailed Description

Class that sets a local variable to True if the object has been deleted.

When using this helper class, create a local eC_Bool variable bDeleted and call InitDeletedFlag() with this variable as the parameter. If the instance of this class gets deleted (the dtor is called), the local variable will be set to true; if the local variable has been set to true the method should return immediately, especially without accessing any variables that are not allocated on its local stack.

Only if the object has not been deleted, call ResetDeletedFlag().

Example:

class MyClass : protected CGUIDeleteNotification
{
    void DoSomething()
    {
        eC_Bool bDeleted;
        InitDeletedFlag(bDeleted);
 
        foo(); // this call may delete "this" object
 
        if (!bDeleted) // the flag has been set to true only if the object was deleted
        {
            ResetDeletedFlag();
            DoSomethingElse();
        }
    }
 
    void DoSomethingElse();
}
