public class WekaGetInstancesValue extends adams.flow.transformer.AbstractTransformer
Retrieves a value from a WEKA Instances object.
Notes:
- date and relational values are forwarded as strings
- missing values are output as '?' (without the single quotes)
Input/output:
- accepts:
weka.core.Instances
- generates:
java.lang.Double
java.lang.String
-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: WekaGetInstancesValue
-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 gets stopped in case this actor encounters an error; useful for critical actors. default: false
-row <adams.core.Index> (property: row) The 1-based index of the row. default: first example: An index is a number starting with 1; the following placeholders can be used as well: first, second, third, last_2, last_1, last
-column <adams.data.weka.WekaAttributeIndex> (property: column) The column to set get the value from. default: first example: An index is a number starting with 1; apart from attribute names (case-sensitive), the following placeholders can be used as well: first, second, third, last_2, last_1, last
