This example is contained in org.eclipse.etrice.examples.dynamicactors3.
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.
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 Container 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.
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.
