Maybe the reference to SQL was misleading. May main question/request is to clear/empty a repository.
Technically this would boil down to using either DELETE or TRUNCATE statements. But what else needs
to be done?

Besides and a clear() method I was thinking also of a purge() method. This would delete physically
all records marked as deleted. But maybe the shouldn't be part of the repository itself, but a part
of a repository service. I think that each repository should have its own service as only the
repository knows what data it stores and how in which tables.
