Enclosing class:

DTMDefaultBaseIterators

public class DTMDefaultBaseIterators.PrecedingIterator
extends DTMDefaultBaseIterators.InternalAxisIteratorBase

Iterator that returns preceding nodes of a given node. This includes the node set {root+1, start-1}, but excludes all ancestors, attributes, and namespace nodes.

Constructor Summary

DTMDefaultBaseIterators.PrecedingIterator()

Method Summary

DTMAxisIterator	cloneIterator() Returns a deep copy of this iterator.
void	gotoMark() Restores the current node remembered by setMark().
boolean	isReverse() True if this iterator has a reversed axis.
int	next() Get the next node in the iteration.
DTMAxisIterator	reset() Resets the iterator to the last start node.
void	setMark() Remembers the current node for the next call to gotoMark().
DTMAxisIterator	setStartNode(int node) Set start to END should 'close' the iterator, i.e. subsequent call to next() should return END.

Constructor Detail

DTMDefaultBaseIterators.PrecedingIterator

public DTMDefaultBaseIterators.PrecedingIterator()

Method Detail

isReverse

public boolean isReverse()

True if this iterator has a reversed axis.

Specified by:

isReverse in interface DTMAxisIterator

Overrides:

isReverse in class DTMAxisIteratorBase

Returns:

true since this iterator is a reversed axis.

cloneIterator

public DTMAxisIterator cloneIterator()

Returns a deep copy of this iterator. The cloned iterator is not reset.

Specified by:

cloneIterator in interface DTMAxisIterator

Overrides:

cloneIterator in class DTMAxisIteratorBase

Returns:

a deep copy of this iterator.

setStartNode

public DTMAxisIterator 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.

Returns:

A DTMAxisIterator set to the start of the iteration.

next

public int next()

Get the next node in the iteration.

Returns:

The next node handle in the iteration, or END.

reset

public DTMAxisIterator reset()

Resets the iterator to the last start node.

Specified by:

reset in interface DTMAxisIterator

Overrides:

reset in class DTMAxisIteratorBase

Returns:

A DTMAxisIterator, which may or may not be the same as this iterator.

setMark

public void setMark()

Description copied from class: DTMDefaultBaseIterators.InternalAxisIteratorBase

Remembers the current node for the next call to gotoMark(). %REVIEW% Should this save _position too?

Specified by:

setMark in interface DTMAxisIterator

Overrides:

setMark in class DTMDefaultBaseIterators.InternalAxisIteratorBase

gotoMark

public void gotoMark()

Description copied from class: DTMDefaultBaseIterators.InternalAxisIteratorBase

Restores the current node remembered by setMark(). %REVEIW% Should this restore _position too?

Specified by:

gotoMark in interface DTMAxisIterator

Overrides:

gotoMark in class DTMDefaultBaseIterators.InternalAxisIteratorBase
