protected SortComponent getSortComponent()
protected boolean isEvaluateNow()
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 evaluateSortComponent(byte evaluation) throws JRException
JRException
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 FillPrepareResult prepare(int availableHeight)
FillComponent
availableHeight
- the amount of vertical space available for the
component, starting from the top of the component element.
public JRFillCloneable createClone(JRFillCloneFactory factory)
public void evaluateDelayedElement(JRPrintElement element, byte evaluation) throws JRException
BaseFillComponent
UnsupportedOperationException
.
If a component supports delayed evaluation, it needs to override this method.
