public class Trigger
extends AbstractTee
implements ActorWithConditionalEquivalent, ActorWithTimedEquivalent

Executes the tee-actor whenever a token gets passed through. In contrast to the Tee actor, it doesn't feed the tee-actor with the current token.

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: Trigger
 

-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.
 

-stop-flow-on-error (property: stopFlowOnError)
    If set to true, the flow gets stopped in case this actor encounters an error;
     useful for critical actors.
 

-tee <adams.flow.core.Actor> [-tee ...] (property: actors)
    The actors to siphon-off the tokens to.
    default:
