      • getTableSourceData

        @Nonnull
public TableData getTableSourceData​(TableSource ts)
                             throws ReportException
        Is called from getReportData to request the data of a single TableSource if the TableSource is not a joined table or view. So it's called for procedures, commands and single tables or views.
        Specified by:
        getTableSourceData in interface DataFactory
        Overrides:
        getTableSourceData in class BaseDataFactory
        Parameters:
        ts - The current table source
        Returns:
        The resulting data, never null.
        Throws:
        ReportException - if error occurs in the API access

      • getReportDataPerInstance

        public boolean getReportDataPerInstance()
        Override this method only if you use subreport(s) and you set the data for the report with the getReportData or DataFactory.fetchData(Engine, FetchTables, DataCollector) method. For more information please refer to the sample Main_and_Subreport_Data_WithExternalResultSet.java.
        With this method you can specify whether the engine should call getReportData per subreport instance or only once for each of the subreports in the executed report. The same subreport can execute multiple time in a report with different parameters depending on its location. A subreport instance means one execution of one subreport. The method should return true if you want to set the different report data depending on the state of the report or if you want to set data depending on one or more parameter values. If you want to set data only once per sub-report, this function must return false. For example if you have a sub-report taking one prompt p0, and getReportDataPerInstance() returns true, then your sub-report will be called $n$ times whenever the value for p0 has been changed. So if your report has sub-reports and your sub-report prompts are linked with fields of the main report and you want to set the data whenever the sub-report prompts change, let getReportDataPerInstance() return true.
        Specified by:
        getReportDataPerInstance in interface DataFactory
        Overrides:
        getReportDataPerInstance in class BaseDataFactory
        Returns:
        true if the engine should invoke getReportData for every subreport instance or false otherwise.
