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 onFillComponent.evaluateDelayedElement(JRPrintElement, byte)
.- Parameters:
evaluation
- the evaluation type- Throws:
JRException
- See Also:
FillContext.evaluate(net.sf.jasperreports.engine.JRExpression, byte)
-
isEvaluateNow
protected boolean isEvaluateNow()
-
evaluateBarcode
protected void evaluateBarcode(byte evaluation)
-
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
-
getTemplateImage
protected JRTemplateImage getTemplateImage()
-
setBarcodeImage
protected void setBarcodeImage(JRTemplatePrintImage image)
-
evaluateDelayedElement
public void evaluateDelayedElement(JRPrintElement element, byte evaluation) throws JRException
Description copied from class:BaseFillComponent
The default implementation throwsUnsupportedOperationException
.If a component supports delayed evaluation, it needs to override this method.
- Specified by:
evaluateDelayedElement
in interfaceFillComponent
- Overrides:
evaluateDelayedElement
in classBaseFillComponent
- Parameters:
element
- the print element for which delayed evaluation has been registeredevaluation
- the evaluation type- Throws:
JRException
- See Also:
FillComponent.evaluate(byte)
