Hi Ufuk, So you want an actor that performs an operation, yet does not fire?
You could try doing some of this work in one of the earlier stages that occurs before firing, such as prefire(). However, there could be issues involving determinancy and endless loops. Parameter evaluation is Ptolemy tries to be lazy, so it might work out ok. Try looking at ptolemy.actor.parameters.SharedParameter ptolemy.actor.parameters.ParameterSet and ptolemy.actor.lib.SetVariable You should also look around for references to ScopeExtendingAttributes. To check if a TypedCompositeEntity has an entity by name, use ptolemy.kernel.CompositeEntity.getEntity(String) To check for a entity of a particular class, see ptolemy.kernel.CompositeEntity.entityList(Class) For further information about traversing a workflow, see volume 2 of the design doc http://ptolemy.berkeley.edu/ptolemyII/designdoc.htm See especially chapter 1, which covers the kernel. _Christopher Ufuk Utku Turuncoglu wrote: > Hi, > > I design an actor (let's say actorA) that creates its parameters > automatically after reading a XML file which is created by another actor > (for example, actorB).
