ABSTRACT:
To enable automatic recovery even of data areas that are referenced from other areas when conducting garbage collection. This memory managing method makes it possible to designate locations in which pointers are contained when securing data areas. Data areas that are referenced from locations that are designated as pointers are not recovered. Rather, data areas that are referenced from locations that are not designated as pointers are recovered when not referenced as pointers from other areas. In addition, the address of a procedure that is called with the address of the data area as a parameter is recorded when this data area is recovered in correspondence with each data area that is the target of management. When it is determined that there are no references to the data area that is the object of management, the procedure that corresponds to that data area is called with the address of that data area as a parameter and following that the data area is recovered.
