@Ser public class WrapperUnit<T extends IUnit> extends Object implements IUnit, com.pnfsoftware.jeb.corei.IWrap<T>
Simple wrapper (decorator) unit that delegates its job to the provided IUnit. This decorator allows the additions of output documents as well as a customization of the unit's format type using the IUnitProvider. For other changes in the IUnit, it is required to extend this class.
