- The pointer list, like the object list, is a list of pointers to
- segment data. Each pointer pointed to must also point within
- segment data, and will be modified by the ORB when copied to point
- to the equivalent location in the destination address space. The
- pointer list must be in order (first by segment, then by address);
- an exception may be thrown if it is out of order of if it contains
- invalid entries. Segments with internal pointers cannot have the
- Shared flag (shared segments can still be pointed to, of course).
- Unmarshalling code should always verify that any internal pointer it
- expects actually points within a valid segment.
+ The object list is a special segment that contains object IDs
+ rather than arbitrary data. Each object ID will be translated
+ into the destination ID-space, allocating new IDs when
+ necessary. The IDs themselves are 32 bits each, unsigned,
+ regardless of the pointer size.
