Class XdmSequenceIterator

  • All Implemented Interfaces:
    java.util.Iterator<XdmItem>

    public class XdmSequenceIterator
    extends java.lang.Object
    implements java.util.Iterator<XdmItem>
    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.

      • hasNext

        public boolean hasNext()
                        throws SaxonApiUncheckedException
        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 interface java.util.Iterator<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

        public XdmItem next()
        Returns the next element in the iteration. Calling this method repeatedly until the hasNext() method returns false will return each element in the underlying collection exactly once.
        Specified by:
        next in interface java.util.Iterator<XdmItem>
        Returns:
        the next element in the iteration.
        Throws:
        java.util.NoSuchElementException - iteration has no more elements.
      • remove

        public void remove()
        Not supported on this implementation.
        Specified by:
        remove in interface java.util.Iterator<XdmItem>
        Throws:
        java.lang.UnsupportedOperationException - always
