Name

adams.flow.transformer.WekaAttributeIterator

Synopsis

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.

Additional information

Flow input/output:
- input: weka.core.Instances, weka.core.Instance
- output: java.lang.String

Options

• loggingLevel
  

  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

  
  
• name
  

  The name of the actor.

  command-line	-name <java.lang.String>
  default	WekaAttributeIterator

  
  
• annotations
  

  The annotations to attach to this actor.

  command-line	-annotation <adams.core.base.BaseAnnotation>
  default

  
  
• skip
  

  If set to true, transformation is skipped and the input token is just forwarded as it is.

  command-line	-skip <boolean>
  default	false

  
  
• stopFlowOnError
  

  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

  
  
• silent
  

  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

  
  
• outputArray
  

  If enabled, outputs the names/indices as an array rather than one-by-one.

  command-line	-output-array <boolean>
  default	false

  
  
• range
  

  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
  example	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

  
  
• regExp
  

  The regular expression used to further limit the attribute set.

  command-line	-regexp <adams.core.base.BaseRegExp>
  default	.*

• outputIndices
  

  If set to true, 1-based indices of matches are output instead of names.

  command-line	-output-indices <boolean>
  default	false
