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
in interfaceweka.core.OptionHandler
- Overrides:
setOptions
in classweka.filters.Filter
- Parameters:
options
- the options to use- Throws:
Exception
-
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
-
getCapabilities
public weka.core.Capabilities getCapabilities()
Returns the Capabilities of this filter.- Specified by:
getCapabilities
in interfaceweka.core.CapabilitiesHandler
- Overrides:
getCapabilities
in classweka.filters.Filter
- Returns:
- the capabilities of this object
- See Also:
Capabilities
-
setColumnFinder
public void setColumnFinder(ColumnFinder value)
Sets the column finder to use.- Parameters:
value
- The column finder to be used (with its options set).
-
getColumnFinder
public ColumnFinder getColumnFinder()
Returns the column finder used by the filter.- Returns:
- The column finder to be used.
-
columnFinderTipText
public abstract String columnFinderTipText()
Returns the tip text for this property.- Returns:

value
- true if to invert the indices
-
getInvert
public boolean getInvert()
Returns whether the invert the column indices.- Returns:
- true if the indices get inverted
-
invertTipText
public String invertTipText()

determineOutputFormat
protected abstract 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., immediateOutputFormat() returns false, then this method will be called from batchFinished().- Specified by:
determineOutputFormat
in classweka.filters.SimpleFilter
- Parameters:
inputFormat
- the input format to base the output format on- Returns:
- the output format
- Throws:
Exception
-
apply
protected abstract weka.core.Instances apply(weka.core.Instances data, int[] indices)
Applies the indices to the data. In case inverting is enabled, the indices have already been inverted.- Parameters:
data
- the data to processindices
- the indices to use- Returns:
- the processed data
-
process
protected weka.core.Instances process(weka.core.Instances instances) throws Exception
Processes the given data (may change the provided dataset) and returns the modified version. This method is called in batchFinished().- Specified by:
process
in classweka.filters.SimpleFilter
- Parameters:
instances
- the data to process- Returns:
- the modified data
- Throws:
Exception
