Field Detail

currentIterator

private int currentIterator

What iterator we are working with now.

iters

private final BooleanIterator[] iters

The iterators that are being sequenced

BooleanCompositeIterator

public BooleanCompositeIterator(BooleanIterator iter)

Initialize this composite to iterate over the given iterator.

BooleanCompositeIterator

public BooleanCompositeIterator(BooleanIterator iter1,
                                BooleanIterator iter2)

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

BooleanCompositeIterator

public BooleanCompositeIterator(BooleanIterator[] iters)

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

BooleanCompositeIterator

protected BooleanCompositeIterator(int currentIterator,
                                   BooleanIterator[] 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?

getBoolean

public boolean getBoolean()
                   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: BooleanIterator

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

Specified by:

clone in interface BooleanIterator

Overrides:

clone in class BooleanAbstractIterator

toString

public String toString()

Overrides:

toString in class Object
