DefaultFlowController

public DefaultFlowController(ReportContext reportContext,
                             ReportJob job)
                      throws DataSourceException

Throws:

DataSourceException

DefaultFlowController

protected DefaultFlowController(DefaultFlowController fc,
                                GlobalMasterRow dataRow)

Method Detail

performOperation

public FlowController performOperation(FlowControlOperation operation)
                                throws DataSourceException

Specified by:

performOperation in interface FlowController

Throws:

DataSourceException

getMasterRow

public GlobalMasterRow getMasterRow()

Specified by:

getMasterRow in interface FlowController

isAdvanceRequested

public boolean isAdvanceRequested()

Specified by:

isAdvanceRequested in interface FlowController

performQuery

public FlowController performQuery(java.lang.String query)
                            throws ReportDataFactoryException,
                                   DataSourceException

This should be called only once per report processing. A JFreeReport object defines the global master report - all other reports are subreport instances.

The global master report receives its parameter set from the Job-Definition, while subreports will read their parameters from the current datarow state.

Specified by:

performQuery in interface FlowController

Parameters:

query -

Returns:

Throws:

ReportDataFactoryException

DataSourceException

performSubReportQuery

public FlowController performSubReportQuery(java.lang.String query,
                                            ParameterMapping[] inputParameters,
                                            ParameterMapping[] outputParameters)
                                     throws ReportDataFactoryException,
                                            DataSourceException

Specified by:

performSubReportQuery in interface FlowController

Throws:

ReportDataFactoryException
