Method Details

initialize
public void initialize(Object node, FlowController flowController, LayoutController parent) throws DataSourceException, ReportDataFactoryException, ReportProcessingException Description copied from class:ElementLayoutController
Initializes the layout controller. This method is called exactly once. It is the creators responsibility to call this method. Calling initialize after the first advance must result in a IllegalStateException.- Specified by:
initialize
in interfaceLayoutController
- Overrides:
initialize
in classElementLayoutController
- Parameters:
node
- the currently processed object or layout node.flowController
- the current flow controller.parent
- the parent layout controller that was responsible for instantiating this controller.- Throws:
DataSourceException
- if there was a problem reading data from the datasource.ReportDataFactoryException
- if a query failed.ReportProcessingException
- if there was a general problem during the report processing.
-
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.
-
join
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.
