    public class WekaClustering
extends AbstractProcessWekaInstanceWithModel<weka.clusterers.Clusterer>
    Uses a serialized model to cluster data being passed through.
    The following order is used to obtain the model (when using AUTO):
    1. model file present?
    2. source actor present?
    3. storage item present?

    Input/output:
    - accepts:
       weka.core.Instance
    - generates:
       adams.flow.container.WekaClusteringContainer


    Container information:
    - adams.flow.container.WekaClusteringContainer: Instance, Cluster, Distribution, LogDensity, LogDensityPerCluster, LogJointDensities 

    -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: WekaClustering
 
    -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.
    default: false
 
    -model-loading-type <AUTO|FILE|SOURCE_ACTOR|STORAGE> (property: modelLoadingType)
    Determines how to load the model, in case of AUTO, first the model file
    is checked, then the callable actor and then the storage.
    default: AUTO
 
    -model <adams.core.io.PlaceholderFile> (property: modelFile)
    The file to load the model from, ignored if pointing to a directory.
    default: ${CWD}
 
    -model-actor <adams.flow.core.CallableActorReference> (property: modelActor)
    The callable actor (source) to obtain the model from, ignored if not present.
    default:
 
    -model-storage <adams.flow.control.StorageName> (property: modelStorage)
    The storage item to obtain the model from, ignored if not present.
    default: storage
 
    -on-the-fly <boolean> (property: onTheFly)
    If set to true, the model file is not required to be present at set up time
    (eg if built on the fly), only at execution time.
    default: false
 
    -use-model-reset-variable <boolean> (property: useModelResetVariable)
    If enabled, chnages to the specified variable are monitored in order to
    reset the model, eg when a storage model changed.
    default: false
 
    -model-reset-variable <adams.core.VariableName> (property: modelResetVariable)
    The variable to monitor for changes in order to reset the model, eg when
    a storage model changed.
    default: variable
