Class ExampleSetAdapter

java.lang.Object
  edu.udo.cs.yale.operator.AbstractIOObject
      edu.udo.cs.yale.operator.ResultObjectAdapter
          edu.udo.cs.yale.example.AbstractExampleSet
              edu.udo.cs.yale.example.ExampleSetAdapter

All Implemented Interfaces:: ExampleSet, IOObject, ResultObject, java.lang.Cloneable, java.lang.Iterable<Example>

Direct Known Subclasses:: AttributeWeightedExampleSet, ConditionedExampleSet, SplittedExampleSet

public class ExampleSetAdapter
extends AbstractExampleSet
extends AbstractExampleSet

This example set delegates all method calls to an underlying example set. Subclasses only need to override necessary methods whose behavior they want to change. Methods implemented by AbstractExampleSet are not re-implemented.
Subclasses usually override iterator(), getExample(int index), size().
