Method Detail
-
setRestartable
public void setRestartable(boolean isRestartable)
Setter for _isRestartable flag.- Specified by:
setRestartable
in interfaceNodeIterator
-
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.- Specified by:
setStartNode
in interfaceNodeIterator
-
reset
public NodeIterator reset()
Reset this iterator using state from last call to setStartNode().- Specified by:
reset
in interfaceNodeIterator
-
includeSelf
public NodeIterator includeSelf()
Setter for _includeSelf flag.
-
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.- Specified by:
getLast
in interfaceNodeIterator
-
getPosition
public int getPosition()
Returns the position() in this iterator.- Specified by:
getPosition
in interfaceNodeIterator
-
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.- Specified by:
isReverse
in interfaceNodeIterator
-
cloneIterator
public NodeIterator cloneIterator()
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.- Specified by:
cloneIterator
in interfaceNodeIterator
