Class Trace<T>

java.lang.Object

gov.nasa.jpf.ListenerAdapter

gov.nasa.jpf.util.Trace<T>

All Implemented Interfaces:

JPFListener, PublisherExtension, SearchListener, VMListener, Iterable<T>

public class Trace<T>
extends ListenerAdapter
implements Iterable<T>

a generic, listener- created trace over property specific operations we could register this as a listener itself, but since it usually is used from a listener, we might as well just delegate from there
