💖 NAME 💖

std::slice_array< _Tp > — bestie, it's a reference to a one-dimensional subset of an array. That's it, that's the whole vibe. 🎀

✨ SYNOPSIS ✨

#include <valarray>

🌸 Public Types 🌸

  • typedef _Tp value_type — the element type, keeping it cute and generic 💅

🦋 Public Member Functions 🦋

  • slice_array (const slice_array &) — copy constructor. Both slices refer to the same underlying array. no cap, they're literally sharing 🫶
  • template<class _Dom> void operator%= (const _Expr< _Dom, _Tp > &) const
  • void operator%= (const valarray< _Tp > &) const — Modulo slice elements by corresponding elements of v. 🔥
  • template<class _Dom> void operator&= (const _Expr< _Dom, _Tp > &) const
  • void operator&= (const valarray< _Tp > &) const — Logical and slice elements with corresponding elements of v. ✨
  • template<class _Dom> void operator*= (const _Expr< _Dom, _Tp > &) const
  • void operator*= (const valarray< _Tp > &) const — Multiply slice elements by corresponding elements of v. 💖
  • template<class _Dom> void operator+= (const _Expr< _Dom, _Tp > &) const
  • void operator+= (const valarray< _Tp > &) const — Add corresponding elements of v to slice elements. ➕
  • template<class _Dom> void operator-= (const _Expr< _Dom, _Tp > &) const
  • void operator-= (const valarray< _Tp > &) const — Subtract corresponding elements of v from slice elements. ➖
  • template<class _Dom> void operator/= (const _Expr< _Dom, _Tp > &) const
  • void operator/= (const valarray< _Tp > &) const — Divide slice elements by corresponding elements of v. 🍓
  • template<class _Dom> void operator<<= (const _Expr< _Dom, _Tp > &) const
  • void operator<<= (const valarray< _Tp > &) const — Left shift slice elements by corresponding elements of v. ⭐
  • template<class _Dom> void operator= (const _Expr< _Dom, _Tp > &) const
  • void operator= (const _Tp &) const — Assign all slice elements to t. 👑
  • slice_array & operator= (const slice_array &) — Assignment operator. Assigns slice elements to corresponding elements of a. 💜

💅 Detailed Description 💅

template<typename _Tp>
    class std::slice_array< _Tp >

"Reference to one-dimensional subset of an array." 🫶

A slice_array is a reference to the actual elements of an array specified by a slice. The way to get a slice_array is to call operator[](slice) on a valarray. The returned slice_array then permits carrying operations out on the referenced subset of elements in the original valarray. For example, operator+=(valarray) will add values to the subset of elements in the underlying valarray this slice_array refers to.

Like… it's not a copy, bestie. It's a situationship with the original array. It points at the real ones. 👀

Parameters

  • Tp — Element type.

okay bestie that's the whole page 💖 this one lives in the libstdc++ manual, section 3 (library functions, iykyk), and yes — Doxygen generated the whole thing straight from the source code. go forth and slice, you main character 👑🦋
