Field Detail

currentIterator

private int currentIterator

What iterator we are working with now.

iters

private final DoubleIterator[] iters

The iterators that are being sequenced

DoubleCompositeIterator

public DoubleCompositeIterator(DoubleIterator iter)

Initialize this composite to iterate over the given iterator.

DoubleCompositeIterator

public DoubleCompositeIterator(DoubleIterator iter1,
                               DoubleIterator iter2)

Initialize this composite to iterate over the given iterators, in order.

DoubleCompositeIterator

public DoubleCompositeIterator(DoubleIterator[] iters)

Initialize this composite to iterate over clones of the given iterators, in order.

DoubleCompositeIterator

protected DoubleCompositeIterator(int currentIterator,
                                  DoubleIterator[] iters)

Initialize this composite to iterate over clones of the given iterators, in order, starting at the given current iterator.

atEnd

public boolean atEnd()

Description copied from interface: IndefiniteIterator

Is this iterator at its end? That is, if we called get(), would it throw an exception?

getDouble

public double getDouble()
                 throws NoSuchElementException

Return the next element in this iteration.

Throws:

NoSuchElementException;

NoSuchElementException

advance

public void advance()

Description copied from interface: IndefiniteIterator

Advance the state of this iteration to the next position. Note that this never throws an exception.

setCurrentIterator

private void setCurrentIterator()

Set the current iterator to the next one that has elements, if any.

clone

public Object clone()

Description copied from interface: DoubleIterator

Return a copy of this iterator in the same state as this object.

Specified by:

clone in interface DoubleIterator

Overrides:

clone in class DoubleAbstractIterator

toString

public String toString()

Overrides:

toString in class Object
