Examples of TerminateProcessException

ptolemy.actor.process.TerminateProcessException
This exception is thrown to terminate a process. This is only a notification exception that a ProcessDirector uses to terminate all the processes gracefully. It is not an exception that indicates an error in the code or model.
In the process domains (PN and CSP for example), a simulation is terminated only when a deadlock is detected. During a deadlock, the threads corresponding to actors are normally blocked on a method call to the receiver. This exception is normally thrown from these methods, so that the threads can return from the call and terminate themselves.
This class is a standalone class and not derived from the Ptolemy Runtime exceptions as those exceptions indicate an error in the model, while this exception is used for passing of information to the threads. @author Neil Smyth, Mudit Goel @version $Id: TerminateProcessException.java,v 1.32 2006/10/02 04:06:15 cxh Exp $ @since Ptolemy II 0.2 @Pt.ProposedRating Green (mudit) @Pt.AcceptedRating Yellow (mudit)
