Method Detail

newInstance

public FeatureGenerator newInstance()

Description copied from class: FeatureGenerator

Subclasses must implement this method so that a new instance of this generator class is returned. The arguments and the example table will not be cloned and thus be null. This kind of clone is needed as generating algorithms must be able to clone generators form their pool without changing the arguments already set for the others.

Specified by:

newInstance in class FeatureGenerator

isCommutative

public boolean isCommutative()

Description copied from class: BinaryNumericalGenerator

Must return true if this generator is commutative.

Specified by:

isCommutative in class BinaryNumericalGenerator

isSelfApplicable

public boolean isSelfApplicable()

Description copied from class: BinaryNumericalGenerator

Must return true if this generator is self applicable.

Specified by:

isSelfApplicable in class BinaryNumericalGenerator

calculateValue

public double calculateValue(double value1,
                             double value2)

Specified by:

calculateValue in class BinaryNumericalGenerator

setFunction

public void setFunction(java.lang.String name)

Description copied from class: FeatureGenerator

Sets the function name. This method is only useful if subclasses can generate more than one function. (like the BasicArithmeticOperationGenerator).

Specified by:

setFunction in class FeatureGenerator

getFunction

public java.lang.String getFunction()

Description copied from class: FeatureGenerator

Sets the function name. This method is only useful if subclasses can generate more than one function. (like the BasicArithmeticOperationGenerator).

Specified by:
