getDesignValue

public Object getDesignValue(ExpressionRuntime runtime,
                             ReportElement element)

Description copied from interface: ElementType

Compute a design-time value. This value will be displayed when editing the element in the Pentaho Report Designer. If there is not enough data available to produce a sensible output, return a mock-object so that the user can interact with the element in a sensible fashion.

When the element is called, all style and attribute expressions have been resolved and can be accessed via the normal static style and attribute accessor methods. If the content of your element depends on style information, the fully computed style must be retrieved via the .Element#getComputedStyle() method. The local style-sheet for the element may not have all information.

Specified by:

getDesignValue in interface ElementType

Parameters:

runtime - the expression runtime holding the current report state.

element - the element.

Returns:

the computed value.

getValue

public Object getValue(ExpressionRuntime runtime,
                       ReportElement element)

Returns the current value for the data source.

Specified by:

getValue in interface DataSource

Parameters:

runtime - the expression runtime that is used to evaluate formulas and expressions when computing the value of this filter.

element - the element from which to read attribute.

Returns:

the value.
