Interface LayoutProcessorFunction

All Superinterfaces:

Cloneable, EventListener, Expression, Function, ReportListener, Serializable

All Known Implementing Classes:

AbstractElementFormatFunction, AttributeExpressionsEvaluator, CellFormatFunction, CreateHyperLinksFunction, ElementColorFunction, ElementTrafficLightFunction, ElementVisibilityFunction, ElementVisibilitySwitchFunction, HideElementByNameFunction, HideElementIfDataAvailableExpression, HideNullValuesFunction, HidePageBandForTableExportFunction, ItemHideFunction, MetaDataStyleEvaluator, NegativeNumberPaintChangeFunction, RowBandingFunction, SheetNameFunction, ShowElementByNameFunction, ShowElementIfDataAvailableExpression, StyleExpressionsEvaluator, StyleResolvingEvaluator, TriggerPageFooterFunction, WizardItemHideFunction

public interface LayoutProcessorFunction
extends Function

A tagging interface that allows the system to differentiate between functions that compute values and functions that modify the report-definiton. Any function that only modifies report definitions and does not return a value that can be in a computation should implement this interface.
