orderBy(o) - JPA CriteriaQuery's method

Specify the ordering expressions that are used to order the query results. Replaces the previous ordering expressions, if any. If no ordering expressions are specified, the previous ordering, if any, is simply removed, and results will be returned in no particular order. The left-to-right sequence of the ordering expressions determines the precedence, whereby the leftmost has highest precedence.
