Method Detail
-
globalInfo
public String globalInfo()
Returns a string describing this filter.- Specified by:
globalInfo
in classweka.filters.SimpleFilter
- Returns:
- a description of the filter suitable for displaying in the explorer/experimenter gui
-
listOptions
public Enumeration<weka.core.Option> listOptions()
Returns an enumeration describing the available options.- Specified by:
listOptions
in interfaceweka.core.OptionHandler
- Overrides:
listOptions
in classweka.filters.Filter
- Returns:
- an enumeration of all the available options.
-
setOptions
public void setOptions(String[] options) throws Exception
Parses a given list of options.- Specified by:
setOptions
in interfaceweka.core.OptionHandler
- Overrides:
setOptions
in classweka.filters.Filter
- Parameters:
options
- the list of options as an array of strings- Throws:
Exception
- if an option is not supported
-
getOptions
public String[] getOptions()
Gets the current settings of the Classifier.- Specified by:
getOptions
in interfaceweka.core.OptionHandler
- Overrides:
getOptions
in classweka.filters.Filter
- Returns:
- an array of strings suitable for passing to setOptions
-
setRange
public void setRange(WekaAttributeRange value)
Sets the attribute range to use.- Parameters:
value
- the range
-
getRange
public WekaAttributeRange getRange()
Returns the attribute range to use.- Returns:
- the range
-
rangeTipText
public String rangeTipText()
Returns the tip text for this property.- Returns:
- tip text for this property suitable for displaying in the GUI or for listing the options.
-
getCapabilities
public weka.core.Capabilities getCapabilities()
Returns the Capabilities of this filter. Derived filters have to override this method to enable capabilities.- Specified by:
getCapabilities
in interfaceweka.core.CapabilitiesHandler
- Overrides:
getCapabilities
in classweka.filters.Filter
- Returns:
- the capabilities of this object
- See Also:
Capabilities
-
reset
protected void reset()
resets the filter, i.e., m_NewBatch to true and m_FirstBatchDone to false.- Overrides:
reset
in classweka.filters.SimpleFilter
-
determineOutputFormat
protected weka.core.Instances determineOutputFormat(weka.core.Instances inputFormat) throws Exception
Determines the output format based on the input format and returns this. In case the output format cannot be returned immediately, i.e., hasImmediateOutputFormat() returns false, then this method will called from batchFinished() after the call of preprocess(Instances), in which, e.g., statistics for the actual processing step can be gathered.- Specified by:
determineOutputFormat
in classweka.filters.SimpleStreamFilter
- Parameters:
inputFormat
- the input format to base the output format on- Returns:
- the output format
- Throws:
Exception
- in case the determination goes wrong- See Also:
SimpleStreamFilter.hasImmediateOutputFormat()
,SimpleStreamFilter.batchFinished()
,SimpleStreamFilter.preprocess(Instances)
-
process
protected weka.core.Instance process(weka.core.Instance instance) throws Exception
processes the given instance (may change the provided instance) and returns the modified version.- Specified by:
process
in classweka.filters.SimpleStreamFilter
- Parameters:
instance
- the instance to process- Returns:
- the modified data
- Throws:
Exception
- in case the processing goes wrong
-
getRevision
public String getRevision()
Returns the revision string.- Specified by:
getRevision
in interfaceweka.core.RevisionHandler
- Overrides:
getRevision
in classweka.filters.Filter
- Returns:
- the revision
-
main
public static void main(String[] args)
Main method for testing this class.- Parameters:
args
- should contain arguments to the filter: use -h for help
