public abstract class NodeIteratorBase extends Object implements NodeIterator

Author: Jacek Ambroziak Santiago Pericas-Geertsen Morten Jorgensen

Method Summary
NodeIterator	cloneIterator() Clones and resets this iterator.
int	getLast() Default implementation of getLast().
int	getPosition() Returns the position() in this iterator.
NodeIterator	includeSelf() Setter for _includeSelf flag.
boolean	isReverse() Indicates if position in this iterator is computed in reverse document order.
NodeIterator	reset() Reset this iterator using state from last call to setStartNode().
void	setRestartable(boolean isRestartable) Setter for _isRestartable flag.
abstract NodeIterator	setStartNode(int node) Initialize iterator using a node.

Clones and resets this iterator. Note that the cloned iterator is not restartable. This is because cloning is needed for variable references, and the context node of the original variable declaration must be preserved.

getLast

public int getLast()

Default implementation of getLast(). Stores current position and current node, resets the iterator, counts all nodes and restores iterator to original state.

getPosition

public int getPosition()

Returns the position() in this iterator.

includeSelf

public NodeIterator includeSelf()

Setter for _includeSelf flag.

isReverse

public boolean isReverse()

Indicates if position in this iterator is computed in reverse document order. Note that nodes are always returned in document order.

reset

public NodeIterator reset()

Reset this iterator using state from last call to setStartNode().

setRestartable

public void setRestartable(boolean isRestartable)

Setter for _isRestartable flag.

setStartNode

public abstract NodeIterator setStartNode(int node)

Initialize iterator using a node. If iterator is not restartable, then do nothing. If node is equal to END then subsequent calls to next() must return END.
