Abstract: MECHANISM AND METHOD FOR ALLOCATING ACTIVE OBJECTS ON A PROCESSOR STACK When an object call from the stack results in the invocation of a hierarchy of class constructs also on the stack, a base class removed more than a predetermined number of levels from the derived class whose member object was called, has no means of directly accessing the originating program to implement an independent task outside the invocation chain. After determining that the data object is constructed on the stack, a mechanism is provided for following the chain of pointers found in the stack frame link records to directly access the originating activation record in the stack for base classes having independent task constructors.
