Tensor DT_STRING createBuffer() doesn't work

[lakshmanok]

This code:

           Tensor fn = new Tensor(tensorflow.DT_STRING, new TensorShape(1));
    CharBuffer buffer = fn.createBuffer();

results in a null buffer. However,

            Tensor fn = new Tensor(tensorflow.DT_FLOAT, new TensorShape(1));
    FloatBuffer buffer = fn.createBuffer();

works fine.

DT_STRING data cannot be represented by primitive types in Java, so we need something else to access it. I've created a StringArray helper class for that in the commit above, so we can do stuff like this:

Tensor x = new Tensor(DT_STRING, new TensorShape(2, 2));
StringArray a = x.createStringArray();
a.position(0).put("foo");
a.position(3).put("bar");
System.out.println(a.position(0)); // prints "foo"

Let me know if that satisfies your needs!

Thanks ... tensorflow.jar that I get from Maven doesn't seem to have been updated?

Need to rebuild from source...

Update binaries are now on the central:

Thanks for reporting this issue!
