Class ModelApplier

java.lang.Object
  edu.udo.cs.yale.operator.Operator
      edu.udo.cs.yale.operator.ModelApplier

All Implemented Interfaces:

ConfigurationListener

public class ModelApplier
extends Operator

This operator applies a Model to an ExampleSet. All parameters of the training process should be stored within the model. However, this operator is able to take any parameters for the rare case that the model can use some parameters during application. Models can be read from a file by using a ModelLoader.

Method Detail

apply

public IOObject[] apply()
                 throws OperatorException

Applies the operator and labels the ExampleSet. The example set in the input is not consumed.

Specified by:

apply in class Operator

Throws:

OperatorException

getInputDescription

public InputDescription getInputDescription(java.lang.Class cls)

Indicates that the consumption of Models can be user defined.

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
