= S =
To convert external names, array indices, or
references within a data structure into address pointers when the
data structure is brought into main memory from external storage
(also called `pointer swizzling'); this may be done for speed in
chasing references or to simplify code (e.g., by turning lots of
name lookups into pointer dereferences). The converse operation is
sometimes termed `unswizzling'. See also snap.
