IOPortEventListener

All Known Implementing Classes:

RemoveIOPortEventListener
```
public interface IOPortEventListener
```
Listen for events that are issued during the send(), broadcast(), sendInside(), get(), getInside() function calls of an IOPort. In general, an object that implements this interface will be collecting tokens for storage.
Currently this class is being used in Kepler by the ProvenanceExecutionListener for saving tokens with provenance information. In the future, listeners will use this interface to save tokens in a cache for use during "smart" reruns or for fault tolerance.
