Dealing with the ORDER BY Clause

If the custom wrapper declares in the CustomWrapperConfiguration that it supports ORDER BY delegations (see section Configuring a Custom Wrapper), the developer can invoke the method getOrderByExpressions() to obtain the expressions in the ORDER BY clause that is delegated to the custom wrapper. This method returns a list of CustomWrapperOrderByExpression objects that have the following attributes:

  • field: the field that the rows should be sorted by.
  • order: the order (ASC or DESC) of the sorting.
