Class CosIdBeforeConvertCallback

java.lang.Object

me.ahoo.cosid.spring.data.jdbc.CosIdBeforeConvertCallback

All Implemented Interfaces:

org.springframework.data.mapping.callback.EntityCallback<Object>, org.springframework.data.relational.core.mapping.event.BeforeConvertCallback<Object>

public class CosIdBeforeConvertCallback
extends Object
implements org.springframework.data.relational.core.mapping.event.BeforeConvertCallback<Object>

Fills the ids of a Spring Data JDBC aggregate before it is converted for an insert: its CosId fields through the runtime's IdFiller, then its @Id property, when still unset, from the idGenerator (as 4.x did with the shared generator). The @Id goes through Spring Data's property accessor, so an immutable aggregate (a record, a wither) comes back as a new instance.

An unset id is null, a number <= 0 or an empty string; long, int and String ids are supported, other id types are left to the application.
