Re: [Boost-users] [Proto] automaitcally convert class to proto literal

Daniel Oberhoff a écrit :

I might have gotten the terms wrong. But the way I got it working now is with using proto::lit which turns things into literals. I tried subclassing terminal with my array class, but that way the tree did not keep a reference to the array, and thus could not be evaluated as such.

Just make a array_data class that contains your data and make your user level array class extends terminal::type. The vec3 example in the doc is exacly this and I used variations of this for like 4 or 5 array like DSEL since proto is available.
