Method Detail

applyOnData

public ExampleSet applyOnData(ExampleSet exampleSet)
                       throws OperatorException

Description copied from class: PreprocessingModel

Applies the model by changing the underlying data

Specified by:

applyOnData in class PreprocessingModel

Throws:

OperatorException

setRanges

public void setRanges(java.util.Map<Attribute,double[]> rangesMap,
                      java.lang.String rangeName,
                      int rangeNameType,
                      int numberOfDigits)
               throws UserError

Creates the ranges. If the range name type is 'Interval' and the number of digits is smaller than 0, the number of digits is automatically determined in a way such that the range names do actually differ but are rounded as far as possible.

Throws:

UserError

setRanges

public void setRanges(java.util.Map<java.lang.String,java.util.SortedSet<Tupel<java.lang.Double,java.lang.String>>> rangesMap)

getRanges

public java.util.Map<java.lang.String,java.util.SortedSet<Tupel<java.lang.Double,java.lang.String>>> getRanges()

toString

public java.lang.String toString()

Specified by:

toString in interface Readable

Overrides:

toString in class java.lang.Object

getTargetAttributes

public Attributes getTargetAttributes(ExampleSet parentSet)

Description copied from interface: ViewModel

This method has to return a legal Attributes object containing every Attribute, the view should contain

Returns:

The attribute object

getValue

public double getValue(Attribute targetAttribute,
                       double value)

Description copied from interface: ViewModel

This method has to provide the attribute value mapping for the view. The views attributes will ask this method for their value.

Parameters:

targetAttribute - the attribute, which asks for his value

value - the value the source attribute had in original data

Returns:

the value the attribute should have in target view
