Method Detail

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

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

toPrintColumn

protected boolean toPrintColumn(BaseColumn column,
                                byte evaluation)
                         throws JRException

Throws:

JRException

evaluateColumns

protected void evaluateColumns(byte evaluation)

createFillSubreport

protected void createFillSubreport()
                            throws JRException

Throws:

JRException

createFillTableSubreport

protected FillTableSubreport createFillTableSubreport()
                                               throws JRException

Throws:

JRException

createTableReportCompileData

protected JRReportCompileData createTableReportCompileData(JasperReport parentReport,
                                                           JRDataset reportSubdataset)
                                                    throws JRException

Throws:

JRException

prepare

public FillPrepareResult prepare(int availableHeight)

Description copied from interface: FillComponent

Prepares to fill the component by deciding whether the component will print, and how much vertical space it will require.

Parameters:

availableHeight - the amount of vertical space available for the component, starting from the top of the component element.

Returns:

the result of the preparation, which specifies whether the component will print and how much it will stretch vertically.

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

getFrameTemplate

protected JRTemplateFrame getFrameTemplate()

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
