org.modeshape.jcr.api.query.qom.QueryObjectModelFactory.descending()

Orders by the value of the specified operand, in descending order. The query is invalid if operand does not evaluate to a scalar value. Null values are returned first; use {@link #descendingNullsLast(DynamicOperand)} for otherbehavior. @param operand the operand by which to order; non-null @return the ordering @throws InvalidQueryException if a particular validity test is possible on this method, the implemention chooses to performthat test (and not leave it until later, on {@link #createQuery}), and the parameters given fail that test @throws RepositoryException if the operation otherwise fails
