<td colspan="5" class="print">0007618: alternative event headers could
allow a boolean combinators</td>
</tr>
<tr class="even print">
<td class="print-category">Description</td>
<td colspan="5" class="print">Sometimes, in an alt statement, different
alternatives have the same alternative body, i.e.<br />
<br />
alt {<br />
[] &lt;event 1&gt; { S }<br />
[] &lt;event 2&gt; { S }<br />
...<br />
}<br />
<br />
In such a case, it would be convenient to only have to write the body
once, e.g.<br />
<br />
alt {<br />
[] &lt;event 1&gt; or &lt;event 2&gt; { S }<br />
...<br />
}<br />
<br />
In a similar fashion, some conditions to be waited on are more complex
and cannot be modeled with a single event, like awaiting two messages
from different ports. Though this can be modeled now by nested alt
statements or using marker flags and the repeat statement (if entering
the alt-branch is undesirable as other alternatives might still be
active in the top-alt which then would need to be copied to the
sub-level alt), it would be more convenient if an and operation could be
employed instead, e.g.<br />
<br />
alt {<br />
[] &lt;event 1&gt; and &lt;event 2&gt; { ... }<br />
}<br />
<br />
Of course, all events treated by such boolean combinations shall be
visible in the same snapshot, so it makes no sense to combine two
receive statements on the same port handling consecutive messages.<br />
<br />
Thus, the proposal is to allow any boolean and/or-combination of allowed
events that can be active in the same snapshot.<br />
<br />
Care must be taken when combining different events with attached
redirects by disjunction as only a subset of the events could be active
and thus only a subset of the redirects might occur, e.g.<br />
<br />
alt {<br />
[] p1.receive(t1) -&gt; value v1 or p2.receive(t2) -&gt; value v2
{<br />
   // here, v1 or v2 might not be bound<br />
}<br />
<br />
Finally, similar to the any from P construct for port arrays, a similar
construct to await a message from all ports in an array might be added,
as well as a base event.<br />
<br />
type record of P Ports;<br />
type record of Message Messages;<br />
<br />
var Ports ports := { p1, p2, p3 }<br />
var Messages v_msgs;<br />
 <br />
alt {<br />
[] all from ports.receive(Message:?) -&gt; value v_msgs[@index] {<br />
// the @index reference allows association of the received
messages<br />
// to the port it was received from, i.e. v_msgs[i] was received from
ports[i]<br />
}<br />
