Hi folks. I have a simple question. Suppose I have a file in disk that has a &quot;pointer&quot; to an object X that is in the image. What can I store from X in the file?  Two options: the address in memory or the hash.<br>
<br>If I savethe address, the object X can be moved by the GC, and thus, the address can become incorrect in the file.  I don&#39;t want to update the disk files in case objects are moved.<br>If I save the hash of X, how can I then localize that object in memory?  Hash is 12 bits...so it is not enough to find that object...(otherwise there would be only 4096 objects)<br>
<br>So....the question is, what should I save from object X in the file and what should I do to be able to localize it, some time after (even when the X is moved by the GC).<br><br>Sorry for my ignorance about the hash. <br>
<br>Thank you very much in advance,<br><br>Mariano<br>
