Variables - How to declare such that evaluation occurs after all records have been processed

[jimy]

Hi, simple question here, I hope:

How do you declare a variable such that the evaluation of that variable does not occur until all records from the DataSource have been processed?

 

Thanks!

OK, I'll try to answer my own question so that it might help others.

1) Define a Scriptlet class and @Override the afterDetailEval() method.
2) Define a Variable(?) and set it's evaluation time to report.
3) Place the variable in the Page Header band.

OK, honestly I have no idea if it matters what band it's in. I tried the Title, Summary, and Page Header. Only page header worked but maybe I screwed something up.

Also I placed a question mark(?) after the word variable in step #2 because I actually used an image with an evaluation time of Report. I think a variable would accomplish the same thing.

Finally, step #1 has nothing to do with when the variable gets evaluated.  But you can use that afterDetailEval() method to set your variable contents.
