MartinsIterationOperator

public MartinsIterationOperator(OperatorDescription description)
Method Detail

apply

public IOObject[] apply()
                 throws OperatorException
Description copied from class: OperatorChain
Applies all inner operators. The input to this operator becomes the input of the first inner operator. The latter's output is passed to the second inner operator and so on. Note to subclassers: If subclasses (for example wrappers) want to make use of this method remember to call exactly this method (super.apply()) and do not call super.apply(IOContainer) erroneously which will result in an infinite loop. Subclasses who override this method without invoking super.apply() should at least invoke the method OperatorChain.clearStepCounter().

Overrides:
apply in class OperatorChain
Returns:
the last inner operator's output or the input itself if the chain is empty.
Throws:
OperatorException


findEnsembleModel

private PredictionModel findEnsembleModel(Model model)

getPerformance

private PerformanceVector getPerformance()
                                  throws OperatorException
Applies the inner operator and employs the PerformanceEvaluator for calculating a list of performance criteria which is returned.

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


getInnerOperatorCondition

public InnerOperatorCondition getInnerOperatorCondition()
Returns a simple chain condition.

Specified by:
getInnerOperatorCondition in class OperatorChain


getMaxNumberOfInnerOperators

public int getMaxNumberOfInnerOperators()
Returns the highest possible value for the maximum number of innner operators.

Specified by:
getMaxNumberOfInnerOperators in class OperatorChain


getMinNumberOfInnerOperators

public int getMinNumberOfInnerOperators()
Returns 1 for the minimum number of innner operators.

Specified by:
getMinNumberOfInnerOperators in class OperatorChain


getNumberOfSteps

public int getNumberOfSteps()
Description copied from class: OperatorChain
Returns the number of steps performed by this chain.

Specified by:
getNumberOfSteps in class OperatorChain


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
