adams.flow.transformer.WekaAttributeIterator
Iterates through all attributes of a dataset and outputs the names.
The attributes can be limited with the range parameter and furthermore with the regular expression applied to the names.
Instead of outputting the names, it is also possible to output the 1-based indices.
Flow input/output:
- input: weka.core.Instances, weka.core.Instance
- output: java.lang.String
The logging level for outputting errors and debugging output.
command-line | -logging-level <OFF|SEVERE|WARNING|INFO|CONFIG|FINE|FINER|FINEST> |
default | WARNING |
min-user-mode | Expert |
The name of the actor.
command-line | -name <java.lang.String> |
default | WekaAttributeIterator |
The annotations to attach to this actor.
command-line | -annotation <adams.core.base.BaseAnnotation> |
default |
|
If set to true, transformation is skipped and the input token is just forwarded as it is.
command-line | -skip <boolean> |
default | false |
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.
command-line | -stop-flow-on-error <boolean> |
default | false |
min-user-mode | Expert |
If enabled, then no errors are output in the console; Note: the enclosing actor handler must have this enabled as well.
command-line | -silent <boolean> |
default | false |
min-user-mode | Expert |
If enabled, outputs the names/indices as an array rather than one-by-one.
command-line | -output-array <boolean> |
default | false |
The range of attributes to iterate over; A range is a comma-separated list of single 1-based indices or sub-ranges of indices ('start-end'); 'inv(...)' inverts the range '...'; the following placeholders can be used as well: first, second, third, last_2, last_1, last.
command-line | -range <adams.core.Range> |
default | first-last |

The regular expression used to further limit the attribute set.
command-line | -regexp <adams.core.base.BaseRegExp> |
default | .* |

If set to true, 1-based indices of matches are output instead of names.
command-line | -output-indices <boolean> |
default | false |
