public class WekaGetInstanceValue extends adams.flow.transformer.AbstractTransformer
Retrieves a value from a WEKA Instance object.
Notes:
- date and relational values are forwarded as strings
- missing values are output as '?' (without the single quotes)
- the 'attribute name' option overrides the 'index' option
Input/output:
- accepts:
weka.core.Instance
- generates:
java.lang.Double
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: WekaGetInstanceValue
-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.
-stop-flow-on-error (property: stopFlowOnError) If set to true, the flow gets stopped in case this actor encounters an error; useful for critical actors.
-index <java.lang.String> (property: index) The 1-based index of the attribute value to retrieve from the WEKA Instance. default: first
-attribute-name <java.lang.String> (property: attributeName) The name of the attribute to get the value for. default:
