Hi Madhavi,
The pseudo code does not give me much to go on.
If you look at the put() method in PNQueueReceiver, then you will see:
while(!_terminate) {
...
try {
...
} catch (InterruptedException e) {
_terminate = true;
} finally {
....
}
}
if (_terminate) {
throw new TerminateProcessException("");
}
Also, reset() sets _terminate to false.
requestFinish() sets _terminate to true.
See the documentation for TerminateProcessException at
http://ptolemy.eecs.berkeley.edu/ptolemyII/ptII8.0/ptII/doc/codeDoc/ptolemy/actor/process/TerminateProcessException.html
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.
The run() method in ptolemy.actor.process.ProcessThread has code like
} else if (thrownWhenIterate instanceof InterruptedException) {
// Process was terminated by call to stop();
if (_debugging) {
_debug("-- Thread was interrupted: "
+ thrownWhenIterate);
}
}
My guess is that PNQueueReceiver.put() may be throwing an
InterruptedException, or PNQueueReceiver.requestFinish() is being called.
I don't see anything obviously wrong with your pseudo code, I suspect
the model has unconnected ports or something?
I would need a complete example to look further into this, there are
just too many possibilities.

Hi Chris,
Thanks for the reply. Following is the illustration for the logic I have.
Public TestActor extends TypedAtomicActor
{
TypedIOPort input, output;
Public TestActor (CompositeEntity container , String name ) throws
IllegalActionException, NameDuplicationException
{
Super ( container, name);
input = createInputPort ( "test");
output = createOutputPort ("test");
}
Public void fire () throws IllegalActionException
{
Super.fire();
If ( some-condition-met)
{
List <IOPort> ports = this.outputPortList();
For (IOPort port : ports )
{
Object value = getValueFor ( port.getName ());
Token token = createTokenFromObject ( value ) ;
port.send (0, token); // THIS LINE IS THROWING TPE
}
}
}
public void postfire() throws IllegalActionException
{
return doWeWantToStop();
}
}
Regards,
Madhavi

sending token from input port to output port
Do you have a small model that illustrates the problem?

Hi,
I am trying to send the token to output port on some conditions
related to my application.
I am using PN director for my workflow and using port.send
(0,token) to send the token to next input port.
I am experiencing the following exception and is blocked on it.
ptolemy.actor.process.TerminateProcessException: Process terminated.

ptolemy.domains.pn.kernel.PNQueueReceiver.put(PNQueueReceiver.java:450)

at ptolemy.actor.TypedIOPort.send(TypedIOPort.java:484)
Have you experienced this problem before? Do you have any
suggestions for this?
Thanks in advance for the help.
