Constructor Summary

Method Summary

void	add(java.lang.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, java.lang.Object value)
int	containsKey(int node, java.lang.Object value)
IntegerArray	getDOMNodeById(java.lang.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.
void	gotoMark() Restores the current node remembered by setMark().
boolean	isReverse() True if this iterator has a reversed axis.
void	lookupId(java.lang.Object value) This method must be called by the code generated by the id() function prior to returning the node iterator.
void	lookupKey(java.lang.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)

KeyIndex

public KeyIndex(int dummy)

Method Detail

setRestartable

public void setRestartable(boolean flag)

Overrides:

setRestartable in class DTMAxisIteratorBase

add

public void add(java.lang.Object value,
                int node)

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

merge

public void merge(KeyIndex other)

Merge the current value's nodeset set by lookupKey() with _nodes.

lookupId

public void lookupId(java.lang.Object value)

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.

getDOMNodeById

public IntegerArray getDOMNodeById(java.lang.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.

lookupKey

public void lookupKey(java.lang.Object value)

This method must be called by the code generated by the key() function prior to returning the node iterator.

next

public int next()

Callers should not call next() after it returns END.

containsID

public int containsID(int node,
                      java.lang.Object value)

containsKey

public int containsKey(int node,
                       java.lang.Object value)

reset

public DTMAxisIterator reset()

Resets the iterator to the last start node.

Overrides:

reset in class DTMAxisIteratorBase

getLast

public int getLast()

Returns the number of elements in this iterator.

Overrides:

getLast in class DTMAxisIteratorBase

getPosition

public int getPosition()

Returns the position of the current node in the set.

Overrides:

getPosition in class DTMAxisIteratorBase

setMark

public void setMark()

Remembers the current node for the next call to gotoMark().

gotoMark

public void gotoMark()

Restores the current node remembered by setMark().

setStartNode

public DTMAxisIterator setStartNode(int start)

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

getStartNode

public int getStartNode()

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

Overrides:

getStartNode in class DTMAxisIteratorBase

isReverse

public boolean isReverse()

True if this iterator has a reversed axis.

Overrides:

isReverse in class DTMAxisIteratorBase

cloneIterator

public DTMAxisIterator cloneIterator()

Returns a deep copy of this iterator.

Overrides:

cloneIterator in class DTMAxisIteratorBase

setDom

public void setDom(DOM dom)
