In addition to the DDF and PN mechanisms others have pointed
to (which conditionally route tokens), there is a new actor
in Ptolemy II called Case, listed in the Ptolemy II default
library under "higher-order components."  This is a composite
actor that can have more than one "inside", and a control port
that determines which inside executes on any given firing...
This works in all domains except CT, but is probably most
useful in SDF, DDF, SR, and DE.  We are working on getting
it to work in CT.
