          com.rapidminer.generator.FloorCeilGenerator

public class FloorCeilGenerator
extends SingularNumericalGenerator

This class has one numerical input attribute and one output attribute. Depending on the mode specified in the constructor the result will be the floor or the ceil function of the input attribute.

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

calculateValue

public double calculateValue(double value)

Description copied from class: SingularNumericalGenerator

Subclasses have to implement this method to calculate the function result.

Specified by:

calculateValue in class SingularNumericalGenerator

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
