void | close() |
Item | current()
Get the current value in the sequence (the one returned by the

Returns: a SequenceIterator that iterates over the same items, positioned before the first item
Throws: net.sf.saxon.trans.XPathException if any error occurs
Returns: the properties of this iterator. This will be some combination of properties such as GROUNDED, LAST_POSITION_FINDER, and LOOKAHEAD. 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 next item, or null if there are no more items.
Throws: net.sf.saxon.trans.XPathException if an error occurs retrieving the next item
Returns: the current position, the position of the item returned by the most recent call of next()
