IPassiveResourceListener

```
public interface IPassiveResourceListener
```
This listener observes a SimPassiveResource. It is being notified whenever a SimulatedProcess requests an arbitrary number of instances of the observed resource, when instances are granted to the requesting process (i.e., the process "acquires" the resource), or when the process releases instances of the resource.
Thus, the methods of this listener are invoked in a fixed order as follows.
1. request
2. acquire
3. release
