template <typename T, typename Cleanup = QScopedPointerArrayDeleter<T>> class QScopedArrayPointer

The QScopedArrayPointer class stores a pointer to a dynamically allocated array of objects, and deletes it upon destruction. More...

## Detailed Description

A QScopedArrayPointer is a QScopedPointer that defaults to deleting the object it is pointing to with the delete[] operator. It also features operator[] for convenience, so we can write:

     void foo()
     {
         QScopedArrayPointer<int> i(new int[10]);
         i[2] = 42;
         ...
         return; // our integer array is now deleted using delete[]
     }

## Member Function Documentation

### QScopedArrayPointer::QScopedArrayPointer()

Constructs a QScopedArrayPointer instance.

### `[explicit]` template <typename D, QScopedArrayPointer<T, Cleanup>::if_same_type<D> = true> QScopedArrayPointer::QScopedArrayPointer(D *p)

Constructs a QScopedArrayPointer and stores the array of objects pointed to by p.

### T &QScopedArrayPointer::operator[](qsizetype i)

Provides access to entry i of the scoped pointer's array of objects.

If the contained pointer is `nullptr`, behavior is undefined.

Note: In Qt versions prior to 6.5, i was of type `int`, not `qsizetype`, possibly causing truncation on 64-bit platforms.

See also isNull().

### const T &QScopedArrayPointer::operator[](qsizetype i) const

Provides access to entry i of the scoped pointer's array of objects.

If the contained pointer is `nullptr` behavior is undefined.

Note: In Qt versions prior to 6.5, i was of type `int`, not `qsizetype`, possibly causing truncation on 64-bit platforms.
