Method Summary | |
---|---|
Value | atomize()
Return the atomized value of the current node.
|
void | close() |
protected VirtualCopy | createCopy(NodeInfo node, NodeInfo root)
Method to create the virtual copy of a node encountered when navigating. |
Item | current()
Get the current item in the sequence.
|
SequenceIterator | getAnother()
Get another iterator over the same sequence of items, positioned at the
start of the sequence
|
int | getProperties()
Get properties of this iterator, as a bit-significant integer.
|
CharSequence | getStringValue()
Return the string value of the current node.
|
AxisIterator | iterateAxis(byte axis, NodeTest test)
Return an iterator over an axis, starting at the current node.
|
boolean | moveNext()
Move to the next node, without returning it. |
Item | next()
Get the next item in the sequence. |
int | position()
Get the current position
|
Returns: the atomized value.
Throws: NullPointerException if there is no current node
Parameters: node the node to be copied root the root of the tree
Returns: the virtual copy
Returns: the current item, that is, the item most recently returned by next()
Returns: a new iterator over the same sequence
Returns: the properties of this iterator. This will be some combination of properties such as VirtualCopier, VirtualCopier, and VirtualCopier. It is always acceptable to return the value zero, indicating that there are no known special properties. It is acceptable for the properties of the iterator to change depending on its state.
Returns: the string value, as an instance of CharSequence.
Throws: NullPointerException if there is no current node
Parameters: axis the axis to iterate over, using a constant such as CHILD test a predicate to apply to the nodes before returning them.
Throws: NullPointerException if there is no current node
Returns: the next Item. If there are no more nodes, return null.
Returns: the position of the current item (the item most recently returned by next()), starting at 1 for the first node
