Name

adams.flow.transformer.MOAInstanceDumper

Synopsis

Dumps MOA Instance objects into an ARFF file. If the headers change and the header-check is enabled, then a new file will be used.
The actor can also turn double arrays into MOA Instance objects (all attributes are assumed to be numeric).

Additional information

Flow input/output:
- input: com.yahoo.labs.samoa.instances.Instance, double[]
- 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	MOAInstanceDumper

  
  
• 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

  
  
• checkHeader
  

  Whether to check the headers - if the headers change, the Instance object gets dumped into a new file.

  command-line	-check <boolean>
  default	false

  
  
• outputPrefix
  

  The path and partial filename of the output file; automatically removes 'arff' and 'csv' extensions, as they get added automatically.

  command-line	-prefix <adams.core.io.PlaceholderFile>
  default	${CWD}

  
  
• outputFormat
  

  The format to output the data in.

  command-line	-format <ARFF|CSV|TAB>
  default	ARFF

  
  
• useRelationNameAsFilename
  

  If set to true, then the relation name replaces the name of the output file; eg if the output file is '/some/where/file.arff' and the relation is 'anneal' then the resulting file name will be '/some/where/anneal.arff'.

  command-line	-use-relation <boolean>
  default	false

  
  
• keepExisting
  

  If enabled, any output file that exists when the actor is executed for the first time (or variables modify the actor) won't get replaced with the current header; useful when outputting data in multiple locations in the flow, but one needs to be cautious as to not stored mixed content (eg varying number of attributes, etc).

  command-line	-keep-existing <boolean>
  default	false

  
  
• bufferSize
  

  The number of instances to buffer before writing to disk, in order to improve I/O performance.

  command-line	-buffer-size <int>
  default	1
  minimum	1
