Class SynchronizedTrainEventVector
java.lang.Object
|
+--TSim.SynchronizedTrainEventVector
- public class SynchronizedTrainEventVector
- extends java.lang.Object
Associated with every train is a position in a vector consisting
of the last error event of that particular train. This makes it
possible to not only report the error on the standard error but
also make future commands affecting the train result in an
exception. Since the number of trains used in the line/run is not
known such a vector need to expand dynamically. This class is a
helper class that does just that.
