Method Detail
-
startData
protected FlowController startData(ReportTarget target, FlowController fc) throws DataSourceException, ReportProcessingException, ReportDataFactoryException
- Overrides:
startData
in classElementLayoutController
- Throws:
DataSourceException
ReportProcessingException
ReportDataFactoryException
-
processContent
protected LayoutController processContent(ReportTarget target) throws DataSourceException, ReportProcessingException, ReportDataFactoryException
Description copied from class:ElementLayoutController
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.- Specified by:
processContent
in classElementLayoutController
- 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.
-
processChild
protected LayoutController processChild(SectionLayoutController derived, Node node, FlowController flowController) throws DataSourceException, ReportProcessingException, ReportDataFactoryException
-
isDisplayable
protected boolean isDisplayable(Node node) throws DataSourceException
- Throws:
DataSourceException
-
finishElement
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 classElementLayoutController
- 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.
-
resetSectionForRepeat
protected void resetSectionForRepeat()
-
finishData
protected FlowController finishData(ReportTarget target, FlowController fc) throws DataSourceException, ReportProcessingException
-
join
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.- Parameters:
flowController
- the flow controller of the parent.- Returns:
- the joined layout controller that incorperates all changes from the delegate.

getNodes
public Node[] getNodes()

getIndex
public int getIndex()
