Karvonite - Agile Persistence Framework

NEW POST: Using Enum?

DiegoCanepa — Thu, 27 Nov 2008 20:27:11 GMT

Hi,
I think it is a bug. The December CTP will be available next week. We'll check it and fix it.

Enums are tracked automatically. There is no need to add them in your PDM. They are treated much like a primitive type.

Thanks for reporting this bug!

NEW POST: Using Enum?

Zyxil — Thu, 27 Nov 2008 17:51:44 GMT

I am attempting to persist a Class that uses a dictionary defined like this:

public Dictionary<GameScreenType, string> ScreenAreas = new Dictionary<GameScreenType, string>();

When I create the ObjectSpace, I get an exception from Karvonite stating that GameScreenType could not be found.

I have not been able to find how to add this type to my persistence model in PMD and PMD does not give any warnings that it should be part of the model.

Are enums tracked automatically as hinted at in the overview pdf? or should they be added to the PMD? and if so, how?

NEW POST: Save to Stream instead of direct to file system

I'd be fine with implementing on my own, but I'd need a way to intercept the serialized ObjectSpace data before it is actually saved to the file system.

CREATED FEATURE: Support for nullable types

Support for nullable types.

Hi Jeff,
This is a corner case scenario. I think you might implement this feature on your own.

We want to keep the Karvonite framework pretty simple,

Hi Jeff,
Those features are currently in our wish list.

NEW POST: Save to Stream instead of direct to file system

Karvonite saves directly to the file system, but could it be extended to include the ability to save to a stream that can then be manipulated by the developer? This could be useful if I want to encrypt the file before saving, or save to isolated storage, or provide some other form of saving the object space data.

NEW POST: How to operate on values returned from GetObjects

jeffdoolittle — Sun, 16 Nov 2008 07:03:41 GMT

even easier:

List<Sprite> list = new List<Sprite>(objectSpace.GetObjects<Sprite>());

and if you've got LINQ (not sure if that is available on XNA or not) you could just do this:

List<Sprite> list = objectSpace.GetObjects<Sprite>().ToList();

I noticed that Nullable types and interfaces cannot be persisted in the October CTP. Do you have any guidance on when these features will be supported in Karvonite?

Thanks,

NEW POST: GetObjects

Thanks!

NEW POST: GetObjects

DiegoCanepa — Sun, 16 Nov 2008 03:29:01 GMT

Yes, the behavior was changed. You can retrieve any object now.

NEW POST: GetObjects

jeffdoolittle — Sun, 16 Nov 2008 00:57:42 GMT

I'm curious if the October CTP now works in the fashion I requested previously. Can I now retrieve indirectly persisted objects using GetObjects<T>()?

Thanks,

--Jeff

EDITED FEATURE: Support for interface references on data members

DiegoCanepa — Fri, 07 Nov 2008 02:29:27 GMT

This new feature will bring support for interface references on data members.

public class MyClass
{
private IMyInterface someField;
}

Although this is a corner case scenario will be adding this new feature in the next CTP.

EDITED FEATURE: Object Identity

DiegoCanepa — Fri, 07 Nov 2008 00:54:02 GMT

Each object has a unique identity within an object library. A new method has been added to the ObjectSpace type that lets you retrieve this unique identity. The object identity might be useful in some rare scenarios.

int identity = os.GetObjectIdentity(someObj);

REOPENED FEATURE: Object Identity

DiegoCanepa — Fri, 07 Nov 2008 00:47:03 GMT

Every object has a unique object identity within an ObjectSpace. A new method has been added to retrieve this unique identity.

int identity = os.GetObjectIdentity(someObj);

UPDATED RELEASE: October (CTP 2008) (Oct 31, 2008)

NEW POST: Information for Newbies

DiegoCanepa — Thu, 06 Nov 2008 13:32:36 GMT

Hi Will,
Karvonite is a single-user persistence framework. We can say that it is much more a serialization engine. I think the LINQ technology is your best choice.

I'm looking for a persistence layer similar to Hibernate which supports SQL Server 2008. Unfortunately, NHibernate (www.nhibernate.org) only supports SQL Server 2000 (and 2005). Does Karvonite support SQL Server 2008? How does Karvonite compare to Hibernate? Where can I find documentation and other information that would help newbies like myself evaluate your product?
