Class XdmSequenceIterator
java.lang.Object
net.sf.saxon.s9api.XdmSequenceIterator
An iterator over an XPath sequence.
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.

Method Details
-
hasNext
Returns true if the iteration has more elements. (In other words, returns true if next would return an element rather than throwing an exception.)- Specified by:
hasNext
in interfaceIterator<XdmItem>
- Returns:
- true if the iterator has more elements.
- Throws:
SaxonApiUncheckedException
- if a dynamic error occurs during XPath evaluation that is detected at this point.
-
next
Returns the next element in the iteration. Calling this method repeatedly until thehasNext()
method returns false will return each element in the underlying collection exactly once.- Specified by:
next
in interfaceIterator<XdmItem>
- Returns:
- the next element in the iteration.
- Throws:
NoSuchElementException
- iteration has no more elements.
-
remove
public void remove()Not supported on this implementation.- Specified by:
remove
in interfaceIterator<XdmItem>
- Throws:
UnsupportedOperationException
