Support for Structures of Arrays

[CharlesSamson]

Hi,
I'm using Structures of Arrays as a point ranges. It would be great if this kind of structure could be supported.

e.g. Simplified SoA as point container :

struct Points
{
    std::vector<float> x;
    std::vector<float> y;
};

Thanks

I think you could write points.x;points.y. Does that help?

[CharlesSamson]

Thanks! This works well for std::vector<float> and float[3]. However, my structure more like a pointer-size pair, like that:

struct Points
{
    float* x;
    float* y;
    size_t size;
}

(Sorry for the previous misleading example).

Eventually, I'd like to add this type to the XML file

<Linestring Type="Points" Id="Points">
  <Points>
    <Array>
      <Pointer>x;y</Pointer> <!-- How to do something like that??? -->
      <Size>size</Size>
    </Array>
  </Points>
</Linestring>

This expression with ; doesn't work in XML. You can pass it the list of watch window.

• ; can be used to define coordinates of points by connecting two containers defining X an Y coordinates separately.
• , can be used to specify the size in case a container is represented by a raw pointer. Btw, this is also supported in VS' watch window.
  So if you have an object of type Points called points and you want to display e.g. 10 first points, you can write:

points.x,10;points.y,10

Unfortunately right now the size has to be specified as number.
