Android POJO Converter:Generate scalable and bindable domain objects java class file automatically in compile time. We always transform data between different layer in Domain-Driven Design, such as VO, PO, DO, DTO, BO. The same situation is often encountered in the development of Android, For example, UserModelDataMapper::transform, UserEntityDataMapper::transform in Android-CleanArchitecture. The process of manually copying and converting is not only cumbersome, but also has a relatively large risk of errors. It also increases maintenance costs when adding or deleting fields. Dozer can be a good solution to this problem, but it may not be applicable on Android.
