Method Detail

getMap

protected MapComponent getMap()

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)

evaluateMap

protected void evaluateMap(byte evaluation)
                    throws JRException

Throws:

JRException

isEvaluateNow

protected boolean isEvaluateNow()

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

evaluateDelayedElement

public void evaluateDelayedElement(JRPrintElement element,
                                   byte evaluation)
                            throws JRException

Description copied from class: BaseFillComponent

The default implementation throws UnsupportedOperationException.

If a component supports delayed evaluation, it needs to override this method.

Specified by:

evaluateDelayedElement in interface FillComponent

Overrides:

evaluateDelayedElement in class BaseFillComponent

Parameters:

element - the print element for which delayed evaluation has been registered

evaluation - the evaluation type

Throws:

JRException

FillComponent.evaluate(byte)

copy

protected void copy(JRGenericPrintElement printElement)
