Class AttributeSetWriter

java.lang.Object
  extended by edu.udo.cs.yale.operator.Operator
      extended by edu.udo.cs.yale.operator.io.AttributeSetWriter
All Implemented Interfaces:
ConfigurationListener

public class AttributeSetWriter
extends Operator

Writes all attributes of an example set to a file. Each line holds the construction description of one attribute. This file can be read in another experiment using the FeatureGenerationOperator or AttributeSetLoader.

AttributeSetWriter

public AttributeSetWriter(OperatorDescription description)
Method Detail

apply

public IOObject[] apply()
                 throws OperatorException
Writes the attribute set to a file.

Specified by:
apply in class Operator
Throws:
OperatorException


getInputClasses

public java.lang.Class[] getInputClasses()
Description copied from class: Operator
Returns the classes that are needed as input. May be null or an empty (no desired input). As default, all delivered input objects are consumed and must be also delivered as output in both Operator.getOutputClasses() and Operator.apply() if this is necessary. This default behavior can be changed by overriding Operator.getInputDescription(Class). Subclasses which implement this method should not make use of parameters since this method is invoked by getParameterTypes(). Therefore, parameters are not fully available at this point of time and this might lead to exceptions. Please use InputDescriptions instead.

Specified by:
getInputClasses in class Operator


getOutputClasses

public java.lang.Class[] getOutputClasses()
Description copied from class: Operator
Returns the classes that are guaranteed to be returned by apply() as additional output. Please note that input object which should not be consumed must also be defined by this method (e.g. for preprocessing operators). The default behavior for input consumation is defined by Operator.getInputDescription(Class) and can be changed by overwriting this method. Objects which are not consumed must not be defined as additional output in this method. May be null or an empy array (no additional output is produced).

Specified by:
getOutputClasses in class Operator


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.

Overrides:
getParameterTypes in class Operator
