Sorry, I thought you wanted to _read_ a MoML file.
You could do something similar to how the
ptII/ptolemy/domains/ct/demo/Helicopter/Helicopter.java
works.
You could create a similar model with domain polymorphic or DE
actors and using the DE Director
Note that if you call
System.out.println(exportMoML());
from within a TypedCompositeActor, then you will get the MoML output.
See also:
ct/demo/Lorenz/Lorenz.java
ct/demo/SigmaDelta/SigmaDelta.java
ct/demo/SquareWave/SquareWave.java
ct/demo/StickyMasses/StickyMasses.java
ct/demo/Thermostat/Thermostat.java
sdf/demo/Butterfly/Butterfly.java
For example, to run the last demo, you would do
java -classpath ptolemy.actor.gui.CompositeActorApplication -class
ptolemy.domains.sdf.demo.Butterfly.Butterfly
The shallow code generator will read in certain models and generate
java files.
(See
http://ptolemy.eecs.berkeley.edu/ptolemyII/ptIIlatest/ptII/doc/codegen.htm)
Below I ran the shallow code generator on
ptII/ptolemy/domains/de/lib/test/auto/Queue.xml
and added "throws" lines so that it would compile
The file is in the ptolemy/copernicus/shallow/cg/Queue
directory, so it is in the ptolemy.copernicus.shallow.cg.Queue package.

All the demo does is run and compare the output against some known
good values.
Obviously, the code is ugly because it is auto generated, but
you can see that we create a DE director and some actors and connect
them.
