getIconLabelComponent

protected IconLabelComponent getIconLabelComponent()

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).

Specified by:

evaluate in interface FillComponent

Parameters:

evaluation - the evaluation type

Throws:

JRException

See Also:

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

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.

Specified by:

fill in interface FillComponent

Returns:

the print element generated by the component

fillHorizontal

public void fillHorizontal()

fillVertical

public void fillVertical()

setStretchHeight

public void setStretchHeight(int stretchHeight)

Specified by:

setStretchHeight in interface StretchableFillComponent

setConditionalStylesContainer

public void setConditionalStylesContainer(JRFillElementContainer conditionalStylesContainer)

Specified by:

setConditionalStylesContainer in interface ConditionalStyleAwareFillComponent

prepare

public FillPrepareResult prepare(int availableHeight)

Specified by:

prepare in interface FillComponent

prepare

public FillPrepareResult prepare(int availableHeight,
 boolean isOverflowAllowed)

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.

Specified by:

prepare in interface FillComponent

Parameters:

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

isOverflowAllowed - flag indicating if overflow is allowed for the component.

Returns:

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

createClone

public JRFillCloneable createClone(JRFillCloneFactory factory)

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

See Also:

• FillComponent.evaluate(byte)

copy

protected void copy(JRGenericPrintElement printElement)

copy

protected void copy(JRPrintFrame printFrame)

getDefaultLineColor

public Color getDefaultLineColor()

Specified by:

getDefaultLineColor in interface JRBoxContainer

getDefaultStyleProvider

public JRDefaultStyleProvider getDefaultStyleProvider()

Specified by:

getDefaultStyleProvider in interface JRStyleContainer

getStyleResolver

protected StyleResolver getStyleResolver()

getStyle

public JRStyle getStyle()

Description copied from interface: JRStyleContainer

Returns this object's style.

Specified by:

getStyle in interface JRStyleContainer

Returns:

this object's style

getStyleNameReference

public String getStyleNameReference()

Description copied from interface: JRStyleContainer

Returns the name of an external style which is to be used by this object.

External styles are defined in templates and are resolved at fill time. This attribute is only effective if no direct style (as returned by getStyle() is specified for this object.

Specified by:

getStyleNameReference in interface JRStyleContainer

Returns:

the name of an external style

getLineBox

public JRLineBox getLineBox()

Specified by:

Description copied from interface: JRImageAlignment

Sets the image horizontal alignment.

Specified by:

setHorizontalImageAlign in interface JRImageAlignment

Parameters:

horizontalAlignment - a value representing one of the horizontal image alignment constants in HorizontalImageAlignEnum
