Death::Containers::ArrayView<const void> class

Constant void array view.

Specialization of ArrayView which is convertible from a compile-time array, Array, ArrayView or StaticArrayView of any type and also any type convertible to them. Size for a particular type is recalculated to a size in bytes. This specialization doesn't provide any accessors besides data(), because it has no use for the void type. Instead, use arrayCast(ArrayView<const void>) to first cast the array to a concrete type and then access the particular elements.

Public types

using Type = const void
Element type.
using Type = const void
Element type.

template<>
Death::Containers::ArrayView<const void>::ArrayView(std::nullptr_t = nullptr) constexpr noexcept

Default constructor.

Creates an empty nullptr view. Copy a non-empty Array or ArrayView onto the instance to make it useful.

template<>
Death::Containers::ArrayView<const void>::ArrayView(const void* data, std::size_t size) constexpr noexcept
