Question

Is there any way to tell db4o to call class default constructor while activating objects? I tried following code but it didn’t work:

    private static void ConfigureDatabase()
    {
        var config = Db4oEmbedded.NewConfiguration();
        config.Common.ObjectClass(typeof(Device)).CallConstructor(true);
        using(var db = Db4oEmbedded.OpenFile(config, Helper.GetDataFilePath("index"))) { }
    }

The constructor of Device is never called when retrieving objects from database.

and here’s how Device constructor looks like:

    public Device()
    {
        connectionType = ConnectionType.Disconnected;
    }

Any help would be appreciated.

UPDATE
BWT, I also wanted to know if it’s possible to tell db4o to call constructor for every objects, without having to write one by one for each type.

Did you try this?

IEmbeddedConfiguration configuration = Db4oEmbedded.NewConfiguration();
configuration.Common.CallConstructors = true;
