Method Detail

next

public DataSet next(int num)

Deprecated.

Like the standard next method but allows a customizable number of examples returned

Specified by:

next in interface DataSetIterator

Parameters:

num - the number of examples

Returns:

the next data applyTransformToDestination

trackEpochs

public void trackEpochs()

Deprecated.

next

public DataSet next()

Deprecated.

Specified by:

next in interface Iterator<DataSet>

inputColumns

public int inputColumns()

Deprecated.

Input columns for the dataset

Specified by:

inputColumns in interface DataSetIterator

Returns:

totalOutcomes

public int totalOutcomes()

Deprecated.

The number of labels for the dataset

Specified by:

totalOutcomes in interface DataSetIterator

Returns:

resetSupported

public boolean resetSupported()

Deprecated.

Specified by:

resetSupported in interface DataSetIterator

asyncSupported

public boolean asyncSupported()

Deprecated.

Specified by:

asyncSupported in interface DataSetIterator

reset

public void reset()

Deprecated.

Resets the iterator back to the beginning

Specified by:

reset in interface DataSetIterator

batch

public int batch()

Deprecated.

Batch size

Specified by:

batch in interface DataSetIterator

Returns:

setPreProcessor

public void setPreProcessor(DataSetPreProcessor preProcessor)

Deprecated.

Specified by:

setPreProcessor in interface DataSetIterator

getLabels

public List<String> getLabels()

Deprecated.

Specified by:

getLabels in interface DataSetIterator

hasNext

public boolean hasNext()

Deprecated.

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

Specified by:

hasNext in interface Iterator<DataSet>

Returns:

true if the iteration has more elements

remove

public void remove()

Deprecated.

Removes from the underlying collection the last element returned by this iterator (optional operation). This method can be called only once per call to next(int). The behavior of an iterator is unspecified if the underlying collection is modified while the iteration is in progress in any way other than by calling this method.

Specified by:

remove in interface Iterator<DataSet>

Throws:

UnsupportedOperationException - if the remove operation is not supported by this iterator

IllegalStateException - if the next method has not yet been called, or the remove method has already been called after the last call to the next method
