    public class TimedTrigger
extends Trigger
implements TimedActor
    Executes the subs-actors whenever a token gets passed through. In contrast to the adams.flow.control.Tee actor, it doesn't feed the sub-actors with the current token.
    Times how long the sub-flow execution takes and sends the time in milli-seconds (as double) in a adams.flow.container.TimingContainer container to the specified callable actor.

    Input/output:
    - accepts:
       adams.flow.core.Unknown
    - generates:
       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: 
 
    -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.
    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: 
 
    -timing-enabled <boolean> (property: timingEnabled)
    If enabled, then the actors performs timing on its execution.
    default: true
 
    -prefix <java.lang.String> (property: prefix)
    The prefix to store in the timing container; automatically expands variables.
    default: 
 
    -callable <adams.flow.core.CallableActorReference> (property: callableName)
    The name of the callable actor to use.
    default: unknown
 
    -optional <boolean> (property: optional)
    If enabled, then the callable actor is optional, ie no error is raised if 
    not found, merely ignored.
    default: false
