Method Detail

save

<T extends PersistableBusinessObject> T save(T bo)

Saves the passed in object via the persistence layer. This will throw an IllegalArgumentException (runtime exception) if the object passed in is not a descendent of BusinessObject.

Parameters:

bo - A BusinessObject instance or descendent that you wish to be stored.

save

List<? extends PersistableBusinessObject> save(List<? extends PersistableBusinessObject> businessObjects)

Saves the businessObjects on the list via the persistence layer. This will throw an IllegalArgumentException (runtime exception) if any of the objects passed in is not a descendent of BusinessObject.

Parameters:

businessObjects - A List of objects to persist.

linkAndSave

PersistableBusinessObject linkAndSave(PersistableBusinessObject bo)

Links up any contained objects, and then Saves the passed in object via the persistence layer. This will throw an IllegalArgumentException (runtime exception) if the object passed in is not a descendent of BusinessObject.

Parameters:

bo - A BusinessObject instance or descendent that you wish to be stored.

linkAndSave

List<? extends PersistableBusinessObject> linkAndSave(List<? extends PersistableBusinessObject> businessObjects)

Links up any contained objects, and Saves the businessObjects on the list via the persistence layer. This will throw an IllegalArgumentException (runtime exception) if any of the objects passed in is not a descendent of BusinessObject.
