public class SetProperty
extends AbstractCallableActorPropertyUpdater
implements InputConsumer, OutputProducer

Sets the property of a callable actor whenever a token passes through.
Note: this actor just sets the value, but performs no re-initialization or similar of the modified object.
The transformer just forwards tokens that it receives after the property has been set.

Input/output:
- accepts:
adams.flow.core.Unknown
- generates:
adams.flow.core.Unknown


Valid options are:

-D <int> (property: debugLevel)
    The greater the number the more additional info the scheme may output to
    the console (0 = off).
    default: 0
    minimum: 0
 

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

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

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

-actor-name <java.lang.String> (property: actorName)
    The name of the global actor to update the property for.
    default: unknown
 

-property <java.lang.String> (property: property)
    The property to update whenever the variable changes.
    default:
