BufferingLayoutController
abstract public class BufferingLayoutController extends AbstractLayoutController (Code)
	Todo: Document me! author: Thomas Morgner since: 05.03.2007

Constructor Summary
protected	BufferingLayoutController()

Method Summary
public LayoutController	advance(ReportTarget target) Advances the processing position. Parameters: target - the report target that receives generated events.
public Object	clone()
abstract protected LayoutController	getInitialDelegate()
public void	initialize(Object node, FlowController flowController, LayoutController parent) Initializes the layout controller.
public boolean	isAdvanceable()
public LayoutController	join(FlowController flowController) Joins with a delegated process flow.
protected LayoutController	joinWithParent() Joins the layout controller with the parent.

Constructor Detail

BufferingLayoutController
protected BufferingLayoutController()(Code)

Method Detail

advance
public LayoutController advance(ReportTarget target) throws DataSourceException, ReportDataFactoryException, ReportProcessingException(Code)
	Advances the processing position. Parameters: target - the report target that receives generated events. the new layout controller instance representing the new state. throws: DataSourceException - if there was a problem reading data fromthe datasource. throws: ReportProcessingException - if there was a general problem duringthe report processing. throws: ReportDataFactoryException - if a query failed.

clone
public Object clone()(Code)

getInitialDelegate
abstract protected LayoutController getInitialDelegate()(Code)

initialize
public void initialize(Object node, FlowController flowController, LayoutController parent) throws DataSourceException, ReportDataFactoryException, ReportProcessingException(Code)
	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. Parameters: node - the currently processed object or layout node. Parameters: flowController - the current flow controller. Parameters: parent - the parent layout controller that was responsible forinstantiating this controller. throws: DataSourceException - if there was a problem reading data fromthe datasource. throws: ReportProcessingException - if there was a general problem duringthe report processing. throws: ReportDataFactoryException - if a query failed.

isAdvanceable
public boolean isAdvanceable()(Code)

join
public LayoutController join(FlowController flowController) throws ReportProcessingException, DataSourceException(Code)
	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. the joined layout controller that incorperates all changes fromthe delegate.

joinWithParent
protected LayoutController joinWithParent() throws ReportProcessingException, ReportDataFactoryException, DataSourceException(Code)
	Joins the layout controller with the parent. This simply calls BufferingLayoutController.join(org.jfree.report.flow.FlowController) on the parent. A join operation is necessary to propagate changes in the flow-controller to the parent for further processing. the joined parent. throws: IllegalStateException - if this layout controller has no parent. throws: org.jfree.report.ReportProcessingException - throws: org.jfree.report.ReportDataFactoryException - throws: org.jfree.report.DataSourceException -
