public class XdmSequenceIterator extends java.lang.Object implements java.util.Iterator<XdmItem>
This class implements the standard Java Iterator interface.
Because the Iterator
interface does not define any checked
exceptions, the hasNext()
method of this iterator throws an unchecked
exception if a dynamic error occurs while evaluating the expression. Applications
wishing to control error handling should take care to catch this exception.
