What is the GenerationProvider for?
The GenerationProvider executes a generation step programmatically – e.g. „create invoice from order“.
execute(source, genClass)
Runs the generation step. Source and generated step class (from the generation.jar) must be type-compatible; returns the created target BO.

public static <S extends BusinessObject, T extends BusinessObject> T
execute(S s, Class<? extends Generation<S,T>> genClass) throws BusinessException; |
| Codeblock |

import org.nuclos.api.provider.GenerationProvider;
public class AuftragAbschliessen implements UpdateFinalRule {
public void updateFinal(UpdateContext context) throws BusinessException {
Auftrag a = context.getBusinessObject(Auftrag.class);
Rechnung r = GenerationProvider.execute(a, ErstelleRechnungAusAuftragGEN.class);
}
} |

|
Due to type safety, wrong source/target types cause compile errors in the rule. |
