Refactor Root

[rpx99]

It seems once there is Data in a store I cannot rename the Root Class.

E.g. I changed

@Storage
public class KundeStorage

to

@Storage
public class DataRoot

Is it possible to use some kind of indirection for this ?
How to fix it, if I ever wanted to do this?

Thanks!

Hey

You have to register a RefactoringMappingProvider, for example:

.createEmbeddedStorageFoundation()
.setRefactoringMappingProvider(
        PersistenceRefactoringMappingProvider.New(
                List.of(KeyValue.New("link.biosmarcel.baka.data.Data", "link.biosmarcel.baka.data.DataNew"))
        )
)

There are multiple ways to do this, but the default seems to be a CSV file, as documented here:
