[Tensorflow] Wrapping tensorflow/core/graph/graph_constructor.h

[pcmoritz]

Thanks a lot for your help so far!

To make modifying existing TensorFlow graphs in Java possible we'd like to wrap

extern Status ConvertGraphDefToGraph(const GraphConstructorOptions& opts,
                                     const GraphDef& gdef, Graph* g);

Unfortunately for this to work I think we also need

std::function<bool(const Node*)> cse_consider_function = nullptr;

from the structs in the same file. I tried

.put(new Info("std::function<bool(const Node*)>").pointerTypes("NodePtrFunc").define())

and then

    public static class NodePtrFunc extends FunctionPointer {
        static { Loader.load(); }
        /** Pointer cast constructor. Invokes {@link Pointer#Pointer(Pointer)}.\                                                                          
         */
        public    NodePtrFunc(Pointer p) { super(p); }
        protected NodePtrFunc() { allocate(); }
        private native void allocate();
        public native @Cast("bool") boolean call(Pointer ptr);
    }

Unfortunately this doesn't seem to work, the Parser seems to have problems with the const (it seems to contract const Node* to constNode*). Any idea how to fix this?

Best,
Philipp.

I've fixed the issue with the const, but that's not enough. I've made those members "write only". We can't convert std::function to a function object or a function pointer like JavaCPP uses right now... Anyway, the consider function looks like a setting for users, right? So, should be OK the way I've put it.

This has been included in the release of version 1.2, so I'm guessing that the above restrictions are satisfactory. Let me know if they are not though, thanks!
