Object Graphs & common functionality

Hello,

As a developer I work a lot with large object graphs (.net objects in my case). For some reason I'm unable to find good information how you would set up a good object graph. Let me explain what I mean by that.

My object graph needs to support for each object:

- Shallow and deep cloning
- Copy and paste parts of the model
- Validation of constraints (business rules)
- Deletion and cascade deletion
- Shallow and deep IEditable support (a way to cancel changes to your object)
- A good pattern to add and remove child objects. (for example remove a employee of a company)
- Support for inverse relations
- For web-applications and remoting stuff objects need to have unique identifiers to manage state-less scenario's
- Support for events (propertychanged, employee added etc)
- Support for dotnet databinding (like the Ibindinglist interface)
- (Optional) support for serialization to XML

Yeah, That's a pretty long list. You can imagine that this is not very easy.

Unfortunately, i never found a good article or documentation about how to implement this (patterns and practices).

Most patterns I know do not consider the whole object graph, making it easy in theory (like memento pattern for cloning) but very difficult to translate into a nig real-world object graph.

How do you handle this? Or do you know a great article or book about this.

Check out CSLA framework at http://www.lhotka.net I am really only beginning to experiment with this myself and would be interested in hearing peoples opinions on this...

The OP reads almost like the spec for the CSLA.NET framework.  I suggest the OP checks it out.

As for using it goes, I'm currently heading up a large  development effort using CSLA.NET and it kicks ass.

Thank you for the link to CSLA.net, looks indeed very similar to what I need, I'm checking it out.

Does anybody now a similar framework in Java?
