+    to UNO objects if you are by definition the owner of that object or

+        take place anymore ).

+
+        <p>After this method has been called, the object should behave as passive
+        as possible, thus it should ignore all calls
+        in case it can comply with its specification (for instance addEventListener()).
+        Often the object can't fulfill its specification anymore,

+        <p>For some objects no real owner can be identified, thus it can be
+        disposed from multiple reference holders. In this case
+        the object should be able to cope with multiple dispose()-calls (which
+        are inevitable in a multithreaded environment).
