I was wondering this as well. It's in Object, so pretty much everything has a data variance attribute and I really don't understand what it could possibly mean in most contexts. For example, in the context of a Geode, I think you are just saying the drawables may change. Ok, fine. What about in the context of a switch node or a group node? Is a dynamic group one in which the membership is variable? How about in the context of a callback? Or an Array? Or a Viewer? Or a RenderStage? It seems to me that it doesn't really belong in Object and perhaps there should be an interface that exposes get and setDataVariance() (and any other data centric accessors). Objects for which data variance makes sense would implement this interface. With similar reasoning, I don't think the resizeGLObjectBuffers() and releaseGLObjects() methods belong in Object either. There must be performance reasons for doing so.
