Examples of client.net.sf.saxon.ce.value.Value.itemAt()

client.net.sf.saxon.ce.value.Value.itemAt()
Get the n'th item in the sequence (starting from 0). This is defined for all Values, but its real benefits come for a sequence Value stored extensionally (or for a MemoClosure, once all the values have been read) @param n position of the required item, counting from zero. @return the n'th item in the sequence, where the first item in the sequence isnumbered zero. If n is negative or >= the length of the sequence, returns null.

        SequenceIterator forwards = operand.iterate(context);
        if ((forwards.getProperties() & SequenceIterator.GROUNDED) != 0) {
            ValueRepresentation repr = ((GroundedIterator)forwards).materialize();
            Value val = Value.asValue(repr);
            int length = val.getLength();
            return val.itemAt(length - 1);
        } else {
            Item current = null;
            while (true) {
                Item item = forwards.next();
                if (item == null) {
