template<unsigned dimensions>
StridedArrayView<dimensions, void> class new in 2020.06
Multi-dimensional void array view with size and stride information.
Specialization of StridedArrayView which is convertible from a compile-time array, Array, ArrayView, StaticArrayView or StridedArrayView of any non-constant type and also any non-constant type convertible to them. For arrays and non-strided views, size is taken as element count of the original array and stride becomes the original type size; for strided views the size and stride is taken as-is. This specialization doesn't provide any accessors besides data(), because it has no use for the void type. Instead, use arrayCast(const StridedArrayView<dimensions, void>&) to first cast the array to a concrete type and then access the particular elements.

Function documentation
template<unsigned dimensions>
Corrade::
Default constructor.
Creates an empty view. Copy a non-empty Array, ArrayView or StridedArrayView onto the instance to make it useful.
template<unsigned dimensions>
Corrade::
Construct a view with explicit size and stride.
| Parameters | |
|---|---|
| data | Continuous view on the data |
| member | Pointer to the first member of the strided view |
| size | Data size |
| stride | Data stride |
The data view is used only for a bounds check — expects that data size is enough for size and stride in the largest dimension if the stride is either positive or negative. Zero strides unfortunately can't be reliably checked for out-of-bounds conditions, so be extra careful when specifying these.
template<unsigned dimensions>
Corrade::
Construct a view with explicit size and stride.
Equivalent to calling StridedArrayView(ArrayView<void>, void*, const Size&, const Stride&) with data as the first parameter and data.data() as the second parameter.
template<unsigned dimensions>
template<class T>
Corrade::
Construct a void view on an array with explicit length.
| Parameters | |
|---|---|
| data | Data pointer |
| size | Data size |
Enabled only on one-dimensional views. Stride is implicitly set to sizeof(T).

template<class T, std::
Construct a void view on a fixed-size array.
| Parameters | |
|---|---|
