| <h4 class="subsectionHead"><span class="titlemark">3.3.1 </span> <a |
| id="x16-720003.3.1"></a>Purpose</h4> |
| <!--l. 182--><p class="noindent" >The example demonstrates the usage of an optional actor array. It is shown that several actor classes derived from the type of |
| the optional actor reference can be created as array members. The array members can be destroyed in arbitrary order and the |
| array size grows and shrinks as appropriate. |
| </p><!--l. 186--><p class="noindent" > |
| </p> |
| <h4 class="subsectionHead"><span class="titlemark">3.3.2 </span> <a |
| id="x16-730003.3.2"></a>Details</h4> |
| <!--l. 188--><p class="noindent" >This example again is similar to example 1. One difference is that the (scalar) optional actor is replaced by a replicated |
| optional actor (or array of optional actors if you wish). The port of the <span |
| class="ec-lmtt-10">Container </span>was also changed to a replicated port. All |
| replication factors in this example are of arbitrary multiplicity (*). The sizes vary dynamically and are unbound as far as the |
| model is concerned. |
| </p><!--l. 193--><p class="noindent" >The behavior was changed to the following: Two instances of different classes are created as members of this array and both |
| are deleted and one is created again. The replicated port is used to send (broadcast) messages to the optional |
| actors. |
| </p><!--l. 197--><p class="noindent" > |
| </p> |
| <h4 class="subsectionHead"><span class="titlemark">3.3.3 </span> <a |
| id="x16-740003.3.3"></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">careful inspection of the console output reveals that objects are created and destroyed as expected</li></ul> |
