public class CartesianToComplex
- extends TypedAtomicActor
Convert a Cartesian pair (represented as two double tokens) to a single
complex token. At each firing of the actor, it will consume exactly one
token from each of the two input ports and produce a complex token on the
output port. The x input becomes the real output and the y input becomes the
imaginary output. If either input port is empty, nothing is produced.

- Overrides:
fire
in class AtomicActor
- Throws:
IllegalActionException
- If there is no director.
prefire
public boolean prefire()
throws IllegalActionException

return what the superclass returns (presumably true).
- Specified by:
prefire
in interface Executable
- Overrides:
prefire
in class AtomicActor
- Returns:
- True if this actor is ready for firing, false otherwise.
- Throws:
