|
/// The Array class requires an array of integers to be passed to the constructor
|
|
/// to specify the dimensions of the Array to be built. C++ does not allow this to
|
|
/// be done in place, and so it typically requires an extra line of code - something
|
|
/// like this:
|
|
///
|
|
/// \code
|
|
/// uint32_t dimensions[3] = {10, 20, 30}; // Array dimensions
|
|
/// Array<3,float> array(dimensions);
|
|
/// \endcode
|
|
///
|
|
/// The ArraySizes class can be constructed in place, and also provides implicit
|
|
/// conversion to an array of integers. Hence it is now possible to declare the
|
|
/// above Array as follows:
|
|
///
|
|
/// \code
|
|
/// Array<3,float> array(ArraySizes(10)(20)(30));
|
|
/// \endcode
|
|
///
|
|
/// Usage of this class is therefore very simple, although the template code
|
|
/// behind it may appear complex. For reference, it is based upon the article here:
|
