public interface ValueConversionContext<P extends PersistentProperty<P>>
ValueConversionContext provides access to the store-specific PersistentProperty and allows to
call the store-default conversion through the read/write methods.
Store implementations should provide their own flavor of ValueConversionContext enhancing the existing API,
implementing delegates for read(Object, TypeInformation), write(Object, TypeInformation).
