public class ConditionalTrigger
extends Trigger
implements BooleanConditionSupporter

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


Conditional equivalent:
adams.flow.control.ConditionalTrigger

-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: ConditionalTrigger
 

-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 gets stopped in case this actor encounters an error;
     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.
    default: false
 

-finish-before-stopping <boolean> (property: finishBeforeStopping)
    If enabled, actor first finishes processing all data before stopping.
    default: false
 

-asynchronous <boolean> (property: asynchronous)
    If enabled, the sub-actors get executed asynchronously rather than the flow 
    waiting for them to finish before proceeding with execution.
    default: false
 

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

-condition <adams.flow.condition.bool.BooleanCondition> (property: condition)
    The boolean condition to evaluate.
    default: adams.flow.condition.bool.Expression
