[Neutron] Exceptions in neutron.extension</font>
<br>
<hr noshade><div><div class="h5">
<br>
<br>
<br><font size="3">Hi stackers,</font>
<br>
<br><font size="3">I notice that there are some exceptions defined in neutron.extension,
and many exceptions are defined in neutron.common.exception. Why they are
defined seperately?</font>
<br>
<br><font size="3">In my opinion:</font>
<br>
<br><font size="3">1) extension will define exception which is only releated
to this extension and is intended to exposed to the client</font>
<br><font size="3">2) exception defined in common.exception will be processed
inside neutron, (It may define some exception releated to specific extension
but the exception will be handled inside neutron.)</font>
<br>
<br><font size="3">I think my understanding is not right, so anyone please
help me.</font>
