+=== Iterating through existing objects ===
+'''getObjects()''' returns a pointer to an [wiki:ObjectListBase], containing all objects of the class. You can iterate through them with an [wiki:Iterator]:
+{{{
+Identifier* identifier = Class(SomeClass);
+
+Iterator it = identifier->getObjects()->begin();
+for (; it != identifier->getObjects()->end(); ++it)
+{
+    it->callAFunction();
+}
+}}}
+
+'''Important''': If you know at compiletime which class you want to iterate through, use [wiki:ObjectListIterator], because it's much faster:
+{{{
+ObjectList<SomeClass>::iterator it = ObjectList<SomeClass>::begin();
+for (; it != ObjectList<SomeClass>::end(); ++it)
+{
+    it->callAFunction();
+}
 }}}
