How To Implement Axis Camera In Iterative Robot

[Radical Pi]

constructors are public (in every program I've seen)

The & makes the variable camera a reference. A reference is similar to a pointer, however once it it set it cannot be changed, and it acts like a non-pointer variable after being set (Use the . operator to access funtions instead of -> )

The camera(AxisCamera::GetInstance()); sets the camera reference to the global AxisCamera object. From that point on if you want to do something like get an image the code is camera.GetImage(imageVar);
