      com.rapidminer.generator.BinaryNumericalGenerator
          com.rapidminer.generator.MinMaxGenerator

public class MinMaxGenerator
extends BinaryNumericalGenerator

This class has two numerical input attributes and one output attribute. Depending on the mode specified in the constructor the result will be the minimum or maximum of the input attributes.

Method Detail

getOutputAttributes

public Attribute[] getOutputAttributes(ExampleTable input)

Description copied from class: FeatureGenerator

Returns the generated attributes types.

Overrides:

getOutputAttributes 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

isCommutative

public boolean isCommutative()

Description copied from class: BinaryNumericalGenerator

Must return true if this generator is commutative.

Specified by:

isCommutative in class BinaryNumericalGenerator

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

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:

getFunction in class FeatureGenerator

equals

public boolean equals(java.lang.Object o)

Description copied from class: FeatureGenerator

A FeatureGenerator equals another FeatureGenerator if its class is equal and its arguments are equal and its function names are equal.

Overrides:

equals in class FeatureGenerator

hashCode

public int hashCode()

Overrides:

hashCode in class FeatureGenerator
