Constructor Detail

ConditionedExampleSet

public ConditionedExampleSet(ExampleSet parent,
                             Condition condition)

Creates a new example which used only examples fulfilling the given condition.

ConditionedExampleSet

public ConditionedExampleSet(ConditionedExampleSet exampleSet)

Clone constructor.

Method Detail

updateCondition

public void updateCondition()

This method should be invoked after changing the condition, i.e. if the acceptance behavior of the condition has changed. This is not necessary for most conditions but might be for conditions which are dynamically changed.

iterator

public java.util.Iterator<Example> iterator()

Returns a ConditionExampleReader.

Specified by:

iterator in interface java.lang.Iterable<Example>

Overrides:

iterator in class ExampleSetAdapter

getExample

public Example getExample(int index)

Returns the i-th example fulfilling the condition.

Specified by:

getExample in interface ExampleSet

Overrides:

getExample in class ExampleSetAdapter

size

public int size()

Counts the number of examples which fulfills the condition.

Specified by:

size in interface ExampleSet

Overrides:

size in class ExampleSetAdapter
