public class ThrowModelError
- extends Sink
An actor that throws a model error when it receives a true token
on any input channel. The message reported in the model error is
given by the message parameter.
The inputs are read and checked in the postfire() method only.
A model error is an exception that is passed up the containment
hierarchy rather than being immediately thrown. Any container
in the containment hierarchy may choose to handle the error.
By default, containers will pass and delegate the error to their
container, if they have one, and throw an exception if they
don't. But some containers might do more with the error.

public ThrowModelError(CompositeEntity container,
java.lang.String name)
throws IllegalActionException,
NameDuplicationException
- Construct an actor in the specified container with the specified
name.
- Parameters:
container - The container.name - The name of this actor within the container.
- Throws:
IllegalActionException - If the actor cannot be contained
by the proposed container.
NameDuplicationException - If the name coincides with
an actor already in the container.
postfire
public boolean postfire()
throws IllegalActionException
- Read one token from each input channel that has a token,
and if any token is true, invoke the model error handler.
- Specified by:
postfire in interface Executable- Overrides:
postfire in class AtomicActor
- Returns:
- Whatever the base class returns (probably true).
- Throws:
IllegalActionException - If thrown by the parent class.
