[jira] Created: (CAY-1545) cayenne-lifecycle Referenceable handler
refactoring
cayenne-lifecycle Referenceable handler refactoring
---------------------------------------------------
Key: CAY-1545
URL: https://issues.apache.org/jira/browse/CAY-1545
Project: Cayenne
Issue Type: Task
Components: Core Library
Affects Versions: 3.1M2
Reporter: Andrus Adamchik
Assignee: Andrus Adamchik
Fix For: 3.1M3
Will change logic in the ReferenceableHandler. Per my experience with Referenceable so far it doesn't make sense to inject a UUID property into the object, as it can be calculated on demand with fairly trivial overhead. So ReferenceableHandler will no longer be a listener that injects UUID, but rather its 'getReferenceable' method will return UUID calculated from ObjectId on the fly.
This also fixes a bug - an exception when extracting UUID from a HOLLOW object, since we can read ObjectId of a HOLLOW object without inflating it form DB.
Finally @Referenceable annotation is no longer needed and can be removed from Cayenne. End users who would still like to inject UUID in their objects, can declare their own annotation and their own listener.

Description:
Will change logic in the ReferenceableHandler. Per my experience with Referenceable so far it doesn't make sense to inject a UUID property into the object, as it can be calculated on demand with fairly trivial overhead. So ReferenceableHandler will no longer be a listener that injects UUID, but rather its 'getReferenceable' method will return UUID calculated from ObjectId on the fly.
This also fixes a bug - an exception when extracting UUID from a HOLLOW object, since we can read ObjectId of a HOLLOW object without inflating it form DB.
Finally @Referenceable annotation is no longer needed and can be removed from Cayenne. After all every single object in Cayenne has ObjectId and hence we can produce a UUID for it. The only current purpose of @Referenceable is therefore to provide UUID as a property (which is not that useful). End users who would still like to inject UUID in their objects, can declare their own annotation and their own listener.
