java.lang.Object
  edu.udo.cs.yale.operator.Operator
      edu.udo.cs.yale.operator.features.selection.AttributeWeightSelection

All Implemented Interfaces:

ConfigurationListener

public class AttributeWeightSelection
extends Operator

This operator selects all attributes which have a weight fulfilling a given condition. For example, only attributes with a weight greater than min_weight should be selected.

Method Summary

IOObject[]	apply() Implement this method in subclasses.
java.lang.Class[]	getInputClasses() Returns the classes that are needed as input.
InputDescription	getInputDescription(java.lang.Class cls) The default implementation returns an input description that consumes the input IOObject without a user parameter.

Method Detail

apply

public IOObject[] apply()
                 throws OperatorException

Description copied from class: Operator

Implement this method in subclasses.

Specified by:

apply in class Operator

Throws:

OperatorException

getInputDescription

public InputDescription getInputDescription(java.lang.Class cls)

Description copied from class: Operator

The default implementation returns an input description that consumes the input IOObject without a user parameter. Subclasses may override this method to allow other input handling behaviors.

Overrides:

getInputDescription in class Operator

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
