Class AttributeWeightsWriter

java.lang.Object
  com.rapidminer.operator.Operator
      com.rapidminer.operator.io.AbstractWriter<AttributeWeights>
          com.rapidminer.operator.io.AttributeWeightsWriter

All Implemented Interfaces:

ConfigurationListener, PreviewListener, ParameterHandler, LoggingHandler

public class AttributeWeightsWriter
extends AbstractWriter<AttributeWeights>

Writes the weights of all attributes of an example set to a file. Therefore a AttributeWeights object is needed in the input of this operator. Each line holds the name of one attribute and its weight. This file can be read in another process using the AttributeWeightsLoader and the AttributeWeightsApplier.

Method Detail

write

public AttributeWeights write(AttributeWeights weights)
                       throws OperatorException

Writes the attribute set to a file.

Specified by:

write in class AbstractWriter<AttributeWeights>

Returns:

the written IOObject itself

Throws:

OperatorException

getParameterTypes

public java.util.List<ParameterType> getParameterTypes()

Description copied from class: Operator

Returns a list of ParameterTypes describing the parameters of this operator. The default implementation returns an empty list if no input objects can be retained and special parameters for those input objects which can be prevented from being consumed.

Specified by:

getParameterTypes in interface ParameterHandler

Overrides:

getParameterTypes in class Operator
