Class SurveyScaleExpression

java.lang.Object

org.jfree.report.expressions.AbstractExpression

org.jfree.report.expressions.ColumnAggregationExpression

org.jfree.report.modules.misc.survey.SurveyScaleExpression

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, Expression

public class SurveyScaleExpression
extends ColumnAggregationExpression
implements java.io.Serializable

An expression that takes values from one or more fields in the current row of the report, builds a SurveyScale instance that will present those values, and returns that instance as the expression result. The fields used by the expression are defined using properties named '0', '1', ... 'N', which need to be specified after the expression is created. These fields should contain Number instances.The SurveyScale class implements the Drawable interface, so it can be displayed using a DrawableElement.

Method Detail

getFieldListParameterPosition

protected int getFieldListParameterPosition()

Specified by:

getFieldListParameterPosition in class ColumnAggregationExpression

getRangeLowerBound

public java.lang.Number getRangeLowerBound()

setRangeLowerBound

public void setRangeLowerBound(java.lang.Number rangeLowerBound)

getRangeUpperBound

public java.lang.Number getRangeUpperBound()

setRangeUpperBound

public void setRangeUpperBound(java.lang.Number rangeUpperBound)

getLowestValue

public int getLowestValue()

setLowestValue

public void setLowestValue(int lowestValue)

getHighestValue

public int getHighestValue()

setHighestValue

public void setHighestValue(int highestValue)

getOverrideShape

public java.awt.Shape getOverrideShape()

Returns the override shape.

Returns:

The override shape (possibly null).

setOverrideShape

public void setOverrideShape(java.awt.Shape shape)

Sets the override shape. The SurveyScale is created with a set of default shapes, this method allows you to clearFromParent the *first* shape if you need to (leave it as null otherwise).

Parameters:

shape - the shape (null permitted).

setOverrideShapeFilled

public void setOverrideShapeFilled(boolean b)

Sets a flag that controls whether the override shape is filled or not.

Parameters:

b - the flag.

computeValue

public java.lang.Object computeValue()
                              throws DataSourceException

Returns a SurveyScale instance that is set up to display the values in the current row.

Specified by:

computeValue in interface Expression

Returns:

a SurveyScale instance.

Throws:

DataSourceException

isOverrideShapeFilled

public boolean isOverrideShapeFilled()

getRangePaint

public java.awt.Paint getRangePaint()

setRangePaint

public void setRangePaint(java.awt.Paint rangePaint)
