AbstractFunction
abstract public class AbstractFunction extends AbstractExpression implements Function(Code)
Base class for implementing new report functions. Provides empty implementations of all the methods in the Function interface.

The function is initialized when it gets added to the report. The method initialize gets called to perform the required initializations. At this point, all function properties must have been set to a valid state and the function must be named. If the initialisation fails, a FunctionInitializeException is thrown and the function get not added to the report.

Constructor Detail
AbstractFunction
protected AbstractFunction()(Code)
Creates an unnamed function. Make sure the name of the function is set using AbstractFunction.setName before the function is added to the report's function collection.



AbstractFunction
protected AbstractFunction(String name)(Code)
Creates an named function.
Parameters:
  name - the name of the function.




Method Detail
groupFinished
public void groupFinished(ReportEvent event)(Code)
Receives notification that a group has finished.
Parameters:
  event - the event.



groupStarted
public void groupStarted(ReportEvent event)(Code)
Receives notification that a group has started.
Parameters:
  event - the event.



itemsAdvanced
public void itemsAdvanced(ReportEvent event)(Code)
Receives notification that a row of data is being processed.
Parameters:
  event - the event.



itemsFinished
public void itemsFinished(ReportEvent event)(Code)
Receives notification that a group of item bands has been completed.

The itemBand is finished, the report starts to close open groups.
Parameters:
  event - The event.




itemsStarted
public void itemsStarted(ReportEvent event)(Code)
Receives notification that a group of item bands is about to be processed.

The next events will be itemsAdvanced events until the itemsFinished event is raised.
Parameters:
  event - The event.




reportDone
public void reportDone(ReportEvent event)(Code)
Receives notification that report generation has completed, the report footer was printed, no more output is done. This is a helper event to shut down the output service.
Parameters:
  event - The event.



reportFinished
public void reportFinished(ReportEvent event)(Code)
Receives notification that the report has finished.
Parameters:
  event - the event.



reportInitialized
public void reportInitialized(ReportEvent event)(Code)
Receives notification that report generation initializes the current run.

The event carries a ReportState.Started state. Use this to initialize the report.
Parameters:
  event - The event.




reportStarted
public void reportStarted(ReportEvent event)(Code)
Receives notification that the report has started.
Parameters:
  event - the event.
