[Bf-committers] Generic Java .blend import/export based on StructDNA

[homac]

Hey there!

This is mainly addressed to *Ton Roosendaal 
<http://wiki.blender.org/index.php/User:Ton>* and *Brecht Van Lommel* 
(i.e. module *Core/Data System/DNA*)

I'm aiming to create a generic (any version) import/export of Blender 
files for Java.

So far, I've developed a tool which uses the type information from your 
StructDNA to generate Java classes which serve as type safe facets to 
access data from .blend files. Finally found a suitable concept for the 
type mapping to Java (considering pointers, type casts and the dirty 
stuff possible in C ;)).

Now, I wanted to add a loader which actually just needs to organise the 
incoming data, which comes in instances of the generated data model, in 
some "Library". The same way as you do it in struct Main (BKE_main.h). 
But I have to admit, that I've got lost in your code there - because you 
are scanning for blocks with IDs "LI" and "ID" which does not exist in 
my reference file (v2.69).

Are those not in all files or is that code for earlier file versions? 
I've read the short intro in blendloader/internal/readfile.c which made 
me confused looking at the content of my file.

Can someone of you give me some (brief) hints on how it is supposed to work?
