Examples of client.net.sf.saxon.ce.value.SequenceExtent

client.net.sf.saxon.ce.value.SequenceExtent
A sequence value implemented extensionally. That is, this class represents a sequence by allocating memory to each item in the sequence.

        SequenceIterator forwards = argument[0].iterate(context);
        return getReverseIterator(forwards);
    }


    public static SequenceIterator getReverseIterator(SequenceIterator forwards) throws XPathException {
        SequenceExtent extent = new SequenceExtent(forwards);
        return extent.reverseIterate();
    }
