public class BooleanSwitch extends TypedAtomicActor implements Rollbackable
Note that the this actor may be used in Synchronous Dataflow (SDF) models, but only under certain circumstances. Specifically, downstream actors will be fired whether a token is sent to them or not. This will only work if the downstream actors specifically check to see whether input tokens are available.

void |
$COMMIT(long timestamp)
Commit changes up to the given timestamp, but not including changes
made at timestamp and afterward.
|
Checkpoint |
$GET$CHECKPOINT()
Get the checkpoint object that monitors this rollbackable object.
|
void |
$RESTORE(long timestamp,
boolean trim)
Restore a previous state to all the private fields of this rollbackable
object.
|
java.lang.Object |
$SET$CHECKPOINT(Checkpoint checkpoint)
Set the checkpoint object of this rollbackable object.
|
java.lang.Object |
clone(Workspace workspace)
Clone this actor into the specified workspace.
|
void |
fire()
Read a token from each input port.
|
void |
initialize()
