Fundamental interface for all database entities. Defines a single generic property: id: I? where I extends Serializable. Extends Serializable. Serves as the base of the entire entity hierarchy — BaseDO, HistoryEntry, and all Hibernate entities implement this interface.
Architecture
Interface Contract
interface IdObject<I : Serializable> : Serializable {
var id: I?
}
Usage in the System
- BaseDO extends
IdObject<I> — all persistent entities
- HistoryEntry extends
IdObject<Long> — history records
- IdOnlySerializer — Jackson serializer that reads
id from any IdObject
- BaseDao — uses
IdObject.serializableId for find/update/delete operations
ID Type Flexibility
I is a generic type parameter bounded by Serializable- Allows Long, Int, String, or composite IDs
- Most entities use
IdObject<Long> after the major migration from Integer to Long IDs
