The Sort class is a JavaBean that abstractly represents the data needed to calculate a sort on some data set. A sort consists of some {@link String} expression and a {@link SortDirection}. The mechanism for performing the sort is not provided here.

A Sort object can be used by some sorting infrastructure to either parameterise a SQL or XQuery query or to simply sort in-memory Java objects. For example, when converting a Sort into a SQL fragment, a Sort with sortExpression "foo" and sortDirection {@link SortDirection#DESCENDING} couldbe converted into:
```
 ORDER BY FOO DESC 
```

    public static boolean isSortedDescending(SortModel sortModel, String sortExpression) {
        if(sortModel == null || sortExpression == null)
            return false;


        Sort sort = sortModel.lookupSort(sortExpression);
        if(sort != null && sort.getDirection() == SortDirection.DESCENDING)
            return true;
        else return false;
    }
