> Project: Isis
> Issue Type: Improvement
> Components: Isis Core
> Reporter: Andi Huber
> Assignee: Andi Huber
> Priority: Major
> Fix For: 2.0.0-M4
>
>
> We are implementing an ObjectManager that is an API to replace
> ObjectAdapterProvider, PersistenceSession and others that are closely coupled
> with JDO.
> Following a chain of responsibility pattern ObjectManager is setup with a
> couple of handlers for different responsibilities, these are:
> 1. Object creation, newing up from a given ObjectSpecification, initializing
> defaults and resolving injection points if required.
> 2. Object re-creation from a given ObjectSpecification + Object-Identifier,
> resolving injection points if required.
> 3. Object persisting for a given ObjectSpecification and the actual Object a
> pojo. Conceptually this might also include aspects of serializing
> ManagedObjects into in-memory mementos.
