Interface IOPortEventListener

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.

Since:

Ptolemy II 7.0
