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

client.net.sf.saxon.ce.value.Value.iterate()
Iterate over the items contained in this value. @return an iterator over the sequence of items @throws XPathException if a dynamic error occurs. This is possible only in the case of valuesthat are materialized lazily, that is, where the iterate() method leads to computation of an expression that delivers the values.

        if (operand instanceof Literal) {
            Value val = ((Literal)operand).getValue();
            if (val instanceof AtomicValue) {
                return operand;
            }
            SequenceIterator iter = val.iterate();
            while (true) {
                // if all items in the sequence are atomic (they generally will be, since this is
                // done at compile time), then return the sequence
                Item i = iter.next();
                if (i == null) {
