execute

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

Using the source object this method runs the given generation and returns the new created target object. The generation is type-safe, which determines the type of the source and the target object

Parameters:

s - - type-specific source-object

genClass - Generation<S,T> - type-specific generation

Returns:

T - target-object

Throws:

BusinessException

execute

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

Using the source objects this method runs the given generation and returns the new created target objects. The generation is type-safe, which determines the type of the source and the target objects.
Note: If the generation object enables 'group by'-functionality, all grouping-arguments will be used. Otherwise for each source a target will be created and returned in the result list.

Parameters:

s - List<S> s - type-specific source-object

genClass - Generation<S,T> genClass - type-specific generation

Returns:

List<T> - List of target-objects

Throws:

BusinessException
