public class UpdateCallableDisplay
extends AbstractActor
implements ControlActor, InputConsumer, OutputProducer

Updates callable display actors that implement adams.flow.core.DataPlotUpdaterHandler.

Input/output:
- accepts:

adams.flow.core.Unknown

-logging-level <OFF|SEVERE|WARNING|INFO|CONFIG|FINE|FINER|FINEST> (property: loggingLevel)
    The logging level for outputting errors and debugging output.
    default: WARNING
 

-name <java.lang.String> (property: name)
    The name of the actor.
    default: UpdateCallableDisplay
 

-annotation <adams.core.base.BaseAnnotation> (property: annotations)
    The annotations to attach to this actor.
    default: 
 

-skip <boolean> (property: skip)
    If set to true, transformation is skipped and the input token is just forwarded 
    as it is.
    default: false
 

-stop-flow-on-error <boolean> (property: stopFlowOnError)
    If set to true, the flow execution at this level gets stopped in case this 
    actor encounters an error; the error gets propagated; useful for critical 
    actors.
    default: false
 

-silent <boolean> (property: silent)
    If enabled, then no errors are output in the console; Note: the enclosing 
    actor handler must have this enabled as well.

-callable <adams.flow.core.CallableActorReference> (property: callableName)
    The name of the callable actor to use.
    default: unknown
