java.lang.Objectnet.sf.saxon.om.ArrayIterator
ArrayIterator is used to enumerate items held in an array. The items are always held in the correct sorted order for the sequence.
Constructor Summary | |
ArrayIterator(Item[] nodes)
Create an iterator over all the items in an array |
|
ArrayIterator(Item[] nodes,
int start,
int end)
Create an iterator over a range of an array. |
Method Summary | |
Item |
current()
Get the current item in the array |
SequenceIterator |
getAnother()
Get another iterator over the same items |
Item[] |
getArray()
Get the underlying array |
int |
getEndPosition()
Get the end position in the array |
int |
getLastPosition()
Get the number of items in the part of the array being processed |
SequenceIterator |
getReverseIterator()
Get an iterator that processes the same items in reverse order |
int |
getStartPosition()
Get the initial start position |
boolean |
hasNext()
Test whether there are any more items |
SequenceIterator |
makeSliceIterator(int min,
int max)
Create a new ArrayIterator over the same items, with a different start point and end point |
Item |
next()
Get the next item in the array |
int |
position()
Get the position of the current item in the array |

public ArrayIterator(Item[] nodes)
nodes
- the array (of any items, not necessarily nodes) to be
processed by the iteratorpublic ArrayIterator(Item[] nodes, int start, int end)
nodes
- the array (of nodes or simple values) to be processed by
the iteratorstart
- the position of the first item to be processed
(numbering from zero)end
- the number of items to be processed; any items after
the n'th are ignoredMethod Detail |
public SequenceIterator makeSliceIterator(int min, int max)
min
- the start position (1-based) of the new ArrayIterator
relative to the originalmax
- the end position (1-based) of the last item to be delivered
by the new ArrayIterator, relative to the original. For example, min=2, max=3
delivers the two items ($base[2], $base[3]). Set this to Integer.MAX_VALUE if
there is no end limit.public boolean hasNext()
