are used to order the buckets.
The expression is evaluated in the context of the crosstab group and can reference measure variables, which evaluate to group totals.
getOrderByExpression
in interface JRCrosstabBucket
public JRExpression getComparatorExpression()
JRCrosstabBucket
The result of this expression is used to sort the buckets, in ascending or
descending order (given by getOrder()
.
If the bucket has an order by expression, the comparator will be used to
compare values as produced by that expression.
If no comparator expression is specified, the natural order will be used.
