Class AxisIter

java.lang.Object

org.basex.query.iter.Iter

org.basex.query.iter.NodeIter

org.basex.query.iter.AxisIter

All Implemented Interfaces:

java.lang.Iterable<ANode>

Direct Known Subclasses:

AxisMoreIter, NodeCache

public abstract class AxisIter
extends NodeIter
implements java.lang.Iterable<ANode>

Interface for light-weight axis iterators, throwing no exceptions. This class also implements the Iterable interface, which is why all of its values can also be retrieved via enhanced for (for-each) loops. Note, however, that using the next() method will give you better performance. Important: to improve performance, this iterator may return the same node instance with updated values. If resulting nodes are to be further processed, they need to be finalized via ANode.finish().
