public class WekaEvaluationValuePicker
extends AbstractTransformer

Picks a specific value from an evaluation object.

Input/output:
- accepts:
weka.classifiers.Evaluation
- generates:
java.lang.Double

Valid options are:

-D (property: debug)
    If set to true, scheme may output additional info to the console.
 

-name <java.lang.String> (property: name)
    The name of the actor.
    default: EvaluationValuePicker
 

-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.
