QueryResult.getNodes() will return bi-directional NodeIterator
implementation.
Bi-directional NodeIterator is not
supported in two following cases:
SQL query: select * from nt:base.
XPath query: //*.
TwoWayRangeIterator interface:
/**
* Skip a number of elements in the iterator.
*
* @param skipNum the non-negative number of elements to skip
* @throws java.util.NoSuchElementException if skipped past the first element
* in the iterator.
*/
public void skipBack(long skipNum);
Usage:
NodeIterator iter = queryResult.getNodes();
while (iter.hasNext()) {
if (skipForward) {
iter.skip(10); // Skip 10 nodes in forward direction
} else if (skipBack) {
TwoWayRangeIterator backIter = (TwoWayRangeIterator) iter;
backIter.skipBack(10); // Skip 10 nodes back
}
.......
}
