Examples of org.exist.xquery.value.PreorderedValueSequence$OrderedNodeProxy

org.exist.xquery.value.PreorderedValueSequence
A sequence that sorts its items in the order specified by the order specs of an "order by" clause. Used by {@link org.exist.xquery.ForExpr}. For better performance, the whole input sequence is sorted in one single step. However, this only works if every order expression returns a result of type node. @author wolf
