| <h4 class="subsectionHead"><span class="titlemark">3.6.2 </span> <a |
| id="x19-850003.6.2"></a>Details</h4> |
| <!--l. 257--><p class="noindent" >In this example the dynamically created actor <span |
| class="ec-lmtt-10">Optional2 </span>has again an optional reference two levels down in its hierarchy. On |
| creation it immediately creates a nested dynamic actor of class <span |
| class="ec-lmtt-10">Optional1 </span>which is sending <span |
| class="ec-lmtt-10">hello() </span>back to the outer |
| <span |
| class="ec-lmtt-10">Container</span>. |
| </p><!--l. 261--><p class="noindent" > |
| </p> |
| <h4 class="subsectionHead"><span class="titlemark">3.6.3 </span> <a |
| id="x19-860003.6.3"></a>Noteworthy</h4> |
| <ul class="itemize1"> |
| <li class="itemize">the generated MSC <span |
| class="ec-lmtt-10">main_Async.seq </span>is a good illustration of the dynamic changes in the system structure |
| </li> |
| <li class="itemize">when a dynamic actor is created its structure is there immediately and all ports are connected. But the initial |
| transition is executed asynchronously. So after the outer dynamic actor is created the port of the <span |
| class="ec-lmtt-10">Container</span> |
| is not yet connected because the initial transition which is responsible for the creation of the inner dynamic |
| actor wasn’t executed yet. So a message sent from this port directly after creation of the outer dynamic actor |
| would get lost.</li></ul> |
