Constructor Detail

BaseFillList

public BaseFillList(ListComponent component,
            JRFillObjectFactory factory)
             throws JRException

Throws:

JRException

Method Detail

createDatasetExpressionEvaluator

protected JRFillExpressionEvaluator createDatasetExpressionEvaluator()

evaluate

public void evaluate(byte evaluation)
              throws JRException

Description copied from interface: FillComponent

Evaluates the fill component.

This method would evaluate the component expressions and store the results to be used in FillComponent.fill().

If the component needs to delay the evaluation of some of its expressions, it would call FillContext.registerDelayedEvaluation(JRPrintElement, EvaluationTimeEnum, String) to register a delayed evaluation print element, and perform the delayed evaluations on FillComponent.evaluateDelayedElement(JRPrintElement, byte).

Parameters:

evaluation - the evaluation type

Throws:

JRException

See Also:

FillContext.evaluate(net.sf.jasperreports.engine.JRExpression, byte)

createPrintFrame

protected void createPrintFrame()

getFrameTemplate

protected JRTemplateFrame getFrameTemplate()

fill

public JRPrintElement fill()

Description copied from interface: FillComponent

Fills the component by creating a print element which will be included in the generated report.

This method will get called only if FillComponent.prepare(int) returned a result that indicated that the component will print.

Returns:

the print element generated by the component

rewind

public void rewind()

Description copied from class: BaseFillComponent

The default implementation is empty.

Override this method if something needs to be done on component rewind.

Specified by:

rewind in interface FillComponent

Overrides:

rewind in class BaseFillComponent
