Class IterableSequenceIterator<T extends Item>

java.lang.Object
net.sf.saxon.tree.jiter.IterableSequenceIterator<T>
Type Parameters:
T - The type of items returned. It is the caller's responsibility to ensure that the supplied SequenceIterator returns items of the correct type.
All Implemented Interfaces:
Iterable<T>, Iterator<T>
public class IterableSequenceIterator<T extends Item> extends Object implements Iterable<T>, Iterator<T>
Wraps a SequenceIterator in a Java iterable, allowing the convenience of processing the items in a Java for-each loop. The iterable can only be used once: it implements both Iterable<T> and Iterator<T>, and throws an exception if the iterator() method is called more than once.
