NodeIteratorBase

public NodeIteratorBase()

Method Detail

setRestartable

public void setRestartable(boolean isRestartable)

Setter for _isRestartable flag.

Specified by:

setRestartable in interface NodeIterator

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 interface NodeIterator

reset

public NodeIterator reset()

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

Specified by:

reset in interface NodeIterator

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 interface NodeIterator

getPosition

public int getPosition()

Returns the position() in this iterator.

Specified by:

getPosition in interface NodeIterator

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 interface NodeIterator

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 interface NodeIterator
