SectionLayoutController
public SectionLayoutController()
startData
protected FlowController startData(ReportTarget target,
FlowController fc)
throws DataSourceException,
ReportProcessingException,
ReportDataFactoryException
- Overrides:
startData
in class ElementLayoutController
- 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 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.
processChild
protected LayoutController processChild(SectionLayoutController derived,
Node node,
FlowController flowController)
throws DataSourceException,
ReportProcessingException,
ReportDataFactoryException
- 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 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 there was an error trying query
data.
resetSectionForRepeat
protected void resetSectionForRepeat()
finishData
protected FlowController finishData(ReportTarget target,
FlowController fc)
throws DataSourceException,
ReportProcessingException
- 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()
setIndex
public void setIndex(int index)
