ArrayListIterator

public ArrayListIterator(List list)

Method Detail

hasNext

public boolean hasNext()

Description copied from interface: LookaheadIterator

Determine whether there are more items to come. Note that this operation is stateless and it is not necessary (or usual) to call it before calling next(). It is used only when there is an explicit need to tell if we are at the last element.

Specified by:

hasNext in interface LookaheadIterator

Returns:

true if there are more nodes

next

public Item next()

Description copied from interface: AxisIterator

Get the next item in the sequence.

Specified by:

next in interface AxisIterator

Specified by:

next in interface SequenceIterator

Returns:

the next Item. If there are no more nodes, return null.

current

public Item current()

Description copied from interface: AxisIterator

Get the current item in the sequence.

Specified by:

current in interface AxisIterator

Specified by:

current in interface SequenceIterator

Returns:

the current item, that is, the item most recently returned by next()

position

public int position()

Description copied from interface: AxisIterator

Get the current position

Specified by:

position in interface AxisIterator

Specified by:

position in interface SequenceIterator

Returns:

the position of the current item (the item most recently returned by next()), starting at 1 for the first node

getLastPosition

public int getLastPosition()

Description copied from interface: LastPositionFinder

Get the last position (that is, the number of items in the sequence)

Specified by:

getLastPosition in interface LastPositionFinder

getAnother

public SequenceIterator getAnother()

Description copied from interface: AxisIterator

Get another iterator over the same sequence of items, positioned at the start of the sequence

Specified by:

getAnother in interface AxisIterator

Specified by:

getAnother in interface SequenceIterator

Returns:

a new iterator over the same sequence
