Method Detail

setData

void setData(weka.core.Instances value)

Sets the original data.

Specified by:

setData in interface SplitGenerator<weka.core.Instances,WekaTrainTestSetContainer>

Parameters:

value - the data

getData

weka.core.Instances getData()

Returns the original data.

Specified by:

getData in interface SplitGenerator<weka.core.Instances,WekaTrainTestSetContainer>

Returns:

the data

initializeIterator

void initializeIterator()

Initializes the iterator (gets implicitly called, when calling next()).

Specified by:

initializeIterator in interface SplitGenerator<weka.core.Instances,WekaTrainTestSetContainer>

hasNext

boolean hasNext()

Returns true if the iteration has more elements. (In other words, returns true if next would return an element rather than throwing an exception.)

Specified by:

hasNext in interface Iterator<WekaTrainTestSetContainer>

Specified by:

hasNext in interface SplitGenerator<weka.core.Instances,WekaTrainTestSetContainer>

Returns:

true if the iterator has more elements.

next

WekaTrainTestSetContainer next()

Returns the next element in the iteration.

Specified by:

next in interface Iterator<WekaTrainTestSetContainer>

Specified by:

next in interface SplitGenerator<weka.core.Instances,WekaTrainTestSetContainer>

Returns:

the next element in the iteration.

Throws:

NoSuchElementException - iteration has no more elements.

remove

void remove()

Unsupported.

Specified by:

remove in interface Iterator<WekaTrainTestSetContainer>

Specified by:

remove in interface SplitGenerator<weka.core.Instances,WekaTrainTestSetContainer>

toString

String toString()

Returns a short description of the generator.

Specified by:

toString in interface SplitGenerator<weka.core.Instances,WekaTrainTestSetContainer>

Overrides:

toString in class Object

Returns:

a short description
