    public class WekaStreamFilter
extends adams.flow.transformer.AbstractTransformerWithPropertiesUpdating
    Filters Instance objects using the specified filter.

    Input/output:
    - accepts:
       weka.core.Instance
       weka.core.Instances
       adams.data.instance.Instance
    - generates:
       weka.core.Instance
       weka.core.Instances
       adams.data.instance.Instance


    -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: WekaStreamFilter
 
    -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
 
    -property <adams.core.base.BaseString> [-property ...] (property: properties)
    The properties to update with the values associated with the specified values.

    default:
 
    -filter <weka.filters.StreamableFilter> (property: filter)
    The stream filter to use for filtering the Instance objects.
