JasperReports defines JRDataSourceProvider interface. But I can not find how JasperReports uses it.

When JasperReports fill data to report, it wants a JRDataSource object, not JRDataSourceProvider.

I wonder JasperReports does not need JRDataSourceProvider at all. It is only for some 3-party tools, such as iReport?

I am using JRDataSourceProvider as datasource for my subreport . Basically the main report data has to be shown as a summary data in the subreport . So i store the Data as collection of type JRDataSourceProvider and pass it to the subreport . The subreport uses this instead of a SQL to display the data.
