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 class 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.

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.
