Unswizzling
In computer science, pointer swizzling is the conversion of references based on name or position into direct pointer references (memory addresses). It is typically performed during deserialization or loading of a relocatable object from a disk file, such as an executable file or pointer-based data structure. The reverse operation, replacing memory pointers with position-independent symbols or positions, is sometimes referred to as unswizzling, and is performed during serialization (saving). Alternatively, both operations can also be referred to as swizzling. Example It is easy to create a linked list data structure using elements like this: struct node ; But saving the list to a file and then reloading it will (on most operating systems) break every link and render the list useless because the nodes will almost never be loaded into the same memory locations. One way to usefully save and retrieve the list is to assign a unique id number to each node and then unswizzle the p ...
