edu.udo.cs.yale.operator.validation.IteratingPerformanceAverage
public class IteratingPerformanceAverage
This operator chain performs the inner operators the given number of times. The inner operators must provide a PerformanceVector. These are averaged and returned as result.

Operator
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.
getInputClasses
in class Operator
public java.lang.Class[] getOutputClasses()
Operator
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).
