Hi Jonathan, Thank you very much. I just realized that the parameter also controls the iterations.

You'll need to control the number of firings by setting the firingCountLimit in your constant (array) actor. I've attached an example. Good luck!

I am using a SDF director to run a simple sequential workflow only once. However, in the middle of the workflow, there would be an actor that outputs an array with arbitrary length. I want to process each element of the array using another actor all in the same iteration, and it seems the easiest way to do that is by using the ArrayToSequence actor. However, the actor requires arrayLength parameter to be set prior to running the workflow. Is there a way to make the arrayLength parameter dynamic and automatically set to the length of the array received by the input port?

This does violate the contract implicit in SDF, though, that each actor has a constant token production and consumption rate. If the actor is only invoked once, though, I doubt that will be a problem. - Sean On Wed, Nov 14, 2012 at 3:23 PM, Alvin Sebastian <[email protected]<mailto:[email protected]>>wrote: > Hi All,**** > > ** ** > > I am a new Kepler user who somehow stuck at how to do a specific thing in > Kepler.**** > > I am using a SDF director to run a simple sequential workflow only once. > However, in the middle of the workflow, there would be an actor that > outputs an array with arbitrary length.

I have looked into IterateOverArray, but the documentation is not very clear and I have no idea at all of how to use it. It has no input nor output ports by default. Setting "enforceArrayLength" to false while using SDF does not work at all. With DDF, it works but it also keeps iterating indefinitely. How do I create a workflow where an actor can consume any number of input token dynamically without keep repeating? As a simple example using SDF director (iterations set to 1), I have a constant actor with value {1,2,3}. I connect the output port of that actor to the input port of ArrayToSequence, and then connect a Display actor to it. What I want is an output of: 1 2 3 whenever I click the run button once. This would be very easy if I set the value of arrayLength to 3, but is there any other way to achieve the same result without having to know the length of the input array before running the workflow?
