protected FlowController finishData(ReportTarget target, FlowController fc) throws DataSourceException, ReportProcessingException
protected LayoutController finishElement(ReportTarget target) throws ReportProcessingException, DataSourceException, ReportDataFactoryException
Finishes the processing of this element. This method is called when the processing state is 'FINISHING'. The element should be closed now and all privatly owned resources should be freed. If the element has a parent, it would be time to join up with the parent now, else the processing state should be set to 'FINISHED'.
- Overrides:
- finishElement in interface ElementLayoutController
- Parameters:
target
- the report target that receives generated events.
- Returns:
- the new layout controller instance representing the new state.
- Throws:
DataSourceException
- if there was a problem reading data from the datasource.ReportProcessingException
- if there was a general problem during the report processing.ReportDataFactoryException
- if there was an error trying query data.
public LayoutController join(FlowController flowController)
Joins with a delegated process flow. This is generally called from a child flow and should *not* (I mean it!) be called from outside. If you do, you'll suffer.
- Specified by:
- join in interface LayoutController
- Parameters:
flowController
- the flow controller of the parent.
- Returns:
- the joined layout controller that incorperates all changes from the delegate.
protected LayoutController processChild(SectionLayoutController derived, Node node, FlowController flowController) throws DataSourceException, ReportProcessingException, ReportDataFactoryException
protected LayoutController processContent(ReportTarget target) throws DataSourceException, ReportProcessingException, ReportDataFactoryException
Processes any content in this element. This method is called when the processing state is 'OPENED'. The returned layout controller will retain the 'OPENED' state as long as there is more content available. Once all content has been processed, the returned layout controller should carry a 'FINISHED' state.
- Overrides:
- processContent in interface ElementLayoutController
- Parameters:
target
- the report target that receives generated events.
- Returns:
- the new layout controller instance representing the new state.
- Throws:
DataSourceException
- if there was a problem reading data from the datasource.ReportProcessingException
- if there was a general problem during the report processing.ReportDataFactoryException
- if a query failed.
protected FlowController startData(ReportTarget target, FlowController fc) throws DataSourceException, ReportProcessingException, ReportDataFactoryException
- Overrides:
- startData in interface ElementLayoutController
