Hi, with the help of Guille I noticed that normal instances usually register weakly:<br><br>TestRunner &gt;&gt; initialize<br>.....<br>SystemAnnouncer current<br>��� ��� weak<br>��� ��� on: ClassAdded, CategoryAdded, ClassRemoved, CategoryRemoved, ClassRenamed, CategoryRenamed, ClassRecategorized send: #update to: self.<br>
.....<br><br>and classes don&#39;t:<br><br>TestCase class &gt;&gt; registerForNotifications<br>��� ...<br>�� SystemAnnouncer current on: MethodAdded, MethodModified, MethodRemoved send: #methodChanged: to: self.<br clear="all">
<br>so..Guille told me this is because usually the cycle-life of instances is short in comparisson with classes. But classes can be removed as well. What happen then? the announcer will hold always a reference to an obsolete class?<br>
my question is, should we always use weakly? if not, why ?<br><br>thanks for the explanation,<br><br>-- <br>Mariano<br><a href="http://marianopeck.wordpress.com" target="_blank">http://marianopeck.wordpress.com</a><br><br>
