public interface LookaheadIterator
- extends SequenceIterator
A SequenceIterator is used to iterate over a sequence. A LookaheadIterator
is one that supports a hasNext() method to determine if there are more nodes
after the current node.
Determine whether there are more items to come.
- Determine whether there are more items to come. Note that this operation
is stateless and it is not necessary (or usual) to call it before calling
next(). It is used only when there is an explicit need to tell if we
are at the last element.
This method must not be called unless the result of getProperties() on the iterator
includes the bit setting
- true if there are more items in the sequence
