All Implemented Interfaces:

Cloneable, DTMAxisIterator

Enclosing class:

DTMDefaultBaseIterators

private final class DTMDefaultBaseIterators.NamespaceChildrenIterator

extends DTMDefaultBaseIterators.InternalAxisIteratorBase

Iterator that returns children within a given namespace for a given node. The functionality chould be achieved by putting a filter on top of a basic child iterator, but a specialised iterator is used for efficiency (both speed and size of translet).

Field Summary

protected int	_currentNode Current iteration location.
private int	_nsType The extended type ID being requested.

Method Summary

void	gotoMark() Restores the current node remembered by setMark().
int	next() Get the next node in the iteration.
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.

Field Detail

_nsType

private final int _nsType

The extended type ID being requested.

_currentNode

protected int _currentNode

Current iteration location. Usually this is the last location returned (starting point for the next() search); for single-node iterators it may instead be initialized to point to that single node.

Constructor Detail

DTMDefaultBaseIterators.NamespaceChildrenIterator

public DTMDefaultBaseIterators.NamespaceChildrenIterator(int type)

Constructor NamespaceChildrenIterator

Parameters:

type - The extended type ID being requested.

Method Detail

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.

setMark

public void setMark()

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

gotoMark

public void gotoMark()

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