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 aSurveyScale
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 containNumber
instances.TheSurveyScale
class implements the Drawable interface, so it can be displayed using a DrawableElement.- See Also:

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. TheSurveyScale
is created with a set of default shapes, this method allows you to clearFromParent the *first* shape if you need to (leave it asnull
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 aSurveyScale
instance that is set up to display the values in the current row.- Specified by:
computeValue
in interfaceExpression
- Returns:
- a
SurveyScale
instance. - Throws:
DataSourceException
