[kepler-dev] Retrieving all the actors available for particular Kepler installation

[Christopher Brooks]

Hi Michal,

I know how it is done in Ptolemy II, and the same techniques should work 
with Kepler.

The set of actors that are available are determined by 
ptolemy.actor.gui.Configuration.

If a model is running in a system that has a Configuration, then to get 
the Configuration:

> <p>To access the configuration from a random place, if you have a
>  NamedObj <code>foo</code>, then you can call:
>  <pre>
>  Effigy effigy = Configuration.findEffigy(foo.toplevel());
>  Configuration configuration = effigy.toplevel();
>  </pre>

Configuration.check() traverses the configuration for various tests, 
below are some fragments from it:

>         // Check TypedAtomicActors and Attributes
>         Iterator containedObjects = deepNamedObjList().iterator();
>         while (containedObjects.hasNext()) {
>             NamedObj containedObject = (NamedObj) containedObjects.next();
Or, to get just the composites:

> for (CompositeEntity composite : deepCompositeEntityList()) {

or

See ptolemy/configs/test/allConfigs.tcl for tests that read the various 
configurations and perform tests on them.

See 
https://kepler-project.org/developers/reference/what-happens-when-kepler-starts-up 
for information about how Kepler starts up and which configuration is read.

There is a chance that Kepler's database adds actors that are not 
accessible via the configuration.
