public interface DTMAxisIterator
extends Cloneable

This class iterates over a single XPath Axis, and returns node handles.

Field Summary

Fields

Modifier and Type	Field	Description
static final int	END	Specifies the end of the iteration, and is the same as DTM.NULL.

Method Summary

Modifier and Type	Method	Description
DTMAxisIterator	cloneIterator()
boolean	isReverse()
int	next()	Get the next node in the iteration.
void	reset()	Resets the iterator to the last start node.
void	setStartNode(int node)	Set start to END should 'close' the iterator, i.e. subsequent call to next() should return END.

Field Details

Method Details

next

int next()

Get the next node in the iteration.

Returns:

The next node handle in the iteration, or END.

reset

void reset()

Resets the iterator to the last start node.

setStartNode

void setStartNode(int node)

Set start to END should 'close' the iterator, i.e. subsequent call to next() should return END.

Parameters:

node - Sets the root of the iteration.

isReverse

boolean isReverse()

Returns:

true if this iterator has a reversed axis, else false.

cloneIterator

DTMAxisIterator cloneIterator()

Returns:

a deep copy of this iterator. The clone should not be reset from its current position.
