Question

我的网络应用中将阿帕奇·卡内用作一种办公室管理,我希望得到一份由凯恩管理的所有实体类别清单(例如[Person.class,Account.class,...])。

我的目标是将这些班级登记在目标设计中;--->PrimaryKey Converter,以便易于处理参数。

我如何这样做?

感谢。

EDIT: I m using Cayenne 3.0

Answer 1

Get a reference the your Datamap by e.g. following the path: DataContext -> EntityResolver -> DataMap
Iterate on all DBEntities or better on all ObjEntities (if they re already mapped - but you can map at runtime dynamically too) - see the methods of DataMap for doing all these operations, such as: DataMap#getObjEntities() or DataMap#getDbEntities() and the others.
For all those properties, there are not only getters but also setters if you want to change something at runtime is not a problem.
