Method Detail |

protected BarbecueComponent getBarcode()
public void evaluate(byte evaluation) throws JRException
FillComponent
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)
.
evaluation
- the evaluation type
JRException
FillContext.evaluate(net.sf.jasperreports.engine.JRExpression, byte)
protected void evaluateBarcode(byte evaluation) throws JRException
JRException
protected boolean isEvaluateNow()
public FillPrepareResult prepare(int availableHeight)
FillComponent
availableHeight
- the amount of vertical space available for the
component, starting from the top of the component element.
public JRPrintElement fill()
FillComponent
This method will get called only if FillComponent.prepare(int)
returned
a result that indicated that the component will print.
public void evaluateDelayedElement(JRPrintElement element, byte evaluation) throws JRException
BaseFillComponent
UnsupportedOperationException
.
If a component supports delayed evaluation, it needs to override this method.
