Dealing with the ORDER BY Clause¶
If the custom wrapper declares in the
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.
