Member Function Documentation

◆ as() [1/2]

template<size_t Sz>

template<typename VecElem , size_t NumElems = SIZE/sizeof(VecElem)>

VecRegT<VecElem, NumElems, true> VecRegContainer< Sz >::as ( ) const

inline

View interposers.

Create a view of this container as a vector of VecElems with an optional amount of elements. If the amount of elements is provided, the size of the container is checked, to test bounds. If it is not provided, the length is inferred from the container size and the element size.

Template Parameters

VecElem	Type of each element of the vector for the view.
NumElem	Amount of elements in the view.
