public class WekaRegexToRange
extends AbstractTransformer

Produces a range string from a regular expression describing attributes.

Input/output:
- accepts:
weka.core.Instance
weka.core.Instances
- generates:
java.lang.String


Valid options are:

-D <int> (property: debugLevel)
    The greater the number the more additional info the scheme may output to
    the console (0 = off).
    default: 0
    minimum: 0
 

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

-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.
 

-regex <java.lang.String> (property: regex)
    The regular expression for attribute matching.
    default: .*
 

-invert (property: invert)
    invert matching sense of regular expression.
