Filtering Data Set programatically

abdullahs

Hi,

I am new to BIRT. Just saw that it has a Data Set filtering feature, using which we can filter the data even after we retrieving it from database.

I want to know if there is any way we can use this filtering feature programatically. So lets say I have a list of maps and I want to apply filtering on this collection ? I can even provide the data in some specific object/format if required by the filtering API.

Can you give a bit more detail? If I wanted to filter a map I would access it in a scripted data source and get my results and apply the filter to the dataset.

Thanks Jason. I am not trying to create a report, what I want to do is I have some in memory data (say a list of maps) and I want to apply filter to this data and get the filtered results. 
 
Its nothing to do with report, but I saw that BIRT has filter API so thought if I could use it for filtering data in my java applicaton.

Understood. I know you do not want to create a report but you could and then run it and extract the data using a data extraction task. You would never have to output it.
