We should look through ptolemy's source and add Kepler library representations for any actors we don't already display and that will work in Kepler. Today the need for some of the Matrix actors came up, and they're two years old, so I suspect there are a number of ptolemy actors we should add. -createActorXML can be used.
We could probably issue a patch to the actors module.

#2 Updated by Daniel Crawl about 10 years ago

I added a new ant target, "find-missing-actors", to list the files of actors, directors, and parameters not in the actor tree, and attached the output to this bug. Christopher, if you tell me what can be added to Kepler, I'll create the metadata files so they appear in the actor tree. Many of the Ptolemy files belong to domains not currently present in Kepler, e.g., SR, Rendezvous, Taskpt, etc. If these are not available in Kepler, then it would be good to update build-area/settings/ptolemy-excludes.

#3 Updated by Christopher Brooks about 10 years ago

The list did not include attributes in vergil/actor/lib?

There are some actors that are listed that are base classes for actors
that are already included.

#4 Updated by Daniel Crawl about 10 years ago

Thanks, Christopher! I added most of the actors and attributes on the list. I also updated ptolemy-excludes.

I couldn't create kar entries for some of the actors because clone() threw an NPE:

[null] java.lang.NullPointerException
[null] at
[null] java.lang.NullPointerException
[null] at
[null] java.lang.NullPointerException
[null] at

#5 Updated by Christopher Brooks about 10 years ago

I added a test that, for each configuration, instantiates an actor and then
calls clone on the actor.

I fixed clone(Workspace) in ptolemy/actor/lib/
and ptolemy/actor/lib/

#6 Updated by Daniel Crawl about 10 years ago

Thanks again, Christopher. After your fix, I was able to add entries for ComputeHistogram, RecursiveLattice, VariableRecursiveLattice, Lattice, and VariableLattice.
