Method Summary
void	add(Object value, int node) Adds a node to the node list for a given value.
DTMAxisIterator	cloneIterator() Returns a deep copy of this iterator.
int	containsID(int node, Object value)
int	containsKey(int node, Object value)
IntegerArray	getDOMNodeById(String id) Return an IntegerArray for the DOM Node which has the given id.
int	getLast() Returns the number of elements in this iterator.
int	getPosition() Returns the position of the current node in the set.
int	getStartNode() Get start to END should 'close' the iterator, i.e. subsequent call to next() should return END.
void	gotoMark() Restores the current node remembered by setMark().
boolean	isReverse() True if this iterator has a reversed axis.
void	lookupId(Object value) This method must be called by the code generated by the id() function prior to returning the node iterator.
void	lookupKey(Object value) This method must be called by the code generated by the key() function prior to returning the node iterator.
void	merge(KeyIndex other) Merge the current value's nodeset set by lookupKey() with _nodes.
int	next() Callers should not call next() after it returns END.
DTMAxisIterator	reset() Resets the iterator to the last start node.
void	setDom(DOM dom)
void	setMark() Remembers the current node for the next call to gotoMark().
void	setRestartable(boolean flag)
DTMAxisIterator	setStartNode(int start) Set start to END should 'close' the iterator, i.e. subsequent call to next() should return END.

Method Detail

add

public void add(Object value, int node)

Adds a node to the node list for a given value. Nodes will always be added in document order.

cloneIterator

public DTMAxisIterator cloneIterator()

Returns a deep copy of this iterator.

containsID

public int containsID(int node, Object value)

containsKey

public int containsKey(int node, Object value)

getDOMNodeById

public IntegerArray getDOMNodeById(String id)

Return an IntegerArray for the DOM Node which has the given id.

Parameters: id The id

Returns: A IntegerArray representing the Node whose id is the given value.

getLast

public int getLast()

Returns the number of elements in this iterator.

getPosition

public int getPosition()

Returns the position of the current node in the set.

getStartNode

public int getStartNode()

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

gotoMark

public void gotoMark()

Restores the current node remembered by setMark().

isReverse

public boolean isReverse()

True if this iterator has a reversed axis.

This method must be called by the code generated by the id() function prior to returning the node iterator. The lookup code for key() and id() differ in the way the lookup value can be whitespace separated list of tokens for the id() function, but a single string for the key() function.
