Method Detail
-
globalInfo
public String globalInfo()
Returns a string describing this classifier.- Specified by:
globalInfo
in classweka.filters.SimpleFilter
- Returns:
- a description of the classifier suitable for displaying in the explorer/experimenter gui
-
getTechnicalInformation
public weka.core.TechnicalInformation getTechnicalInformation()
Returns an instance of a TechnicalInformation object, containing detailed information about the technical background of this class, e.g., paper reference or book this class is based on.- Specified by:
getTechnicalInformation
in interfaceweka.core.TechnicalInformationHandler
- Returns:
- the technical information about this class
-
listOptions
public Enumeration 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 list of options for this object. Also resets the state of the filter (this reset doesn't affect the 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- See Also:
SimpleFilter.reset()
-
getOptions
public String[] getOptions()
Gets the current settings of the filter.- Specified by:
getOptions
in interfaceweka.core.OptionHandler
- Overrides:
getOptions
in classweka.filters.Filter
- Returns:
- an array of strings suitable for passing to setOptions
-
setNumPoints
public void setNumPoints(int value)
Sets the number of points to generate.- Parameters:
value
- the number of points
-
getNumPoints
public int getNumPoints()
Returns the number of points to generate.- Returns:
- the number of points
-
numPointsTipText
public String numPointsTipText()
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
-
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
-
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
